According to the given information, on gradually increasing the temperature of a substance, its color becomes white. This phenomenon can be explained by understanding the concept of incandescence and the relationship between temperature and color.

Incandescence:
Incandescence refers to the emission of visible light by a heated object. When an object is heated, its atoms and molecules gain energy, causing them to vibrate and move faster. As a result, they emit photons of light. The color of the light emitted depends on the temperature of the object.

Relationship between Temperature and Color:
As the temperature of an object increases, the average energy of the emitted photons also increases. This leads to a shift in the color of the emitted light. The phenomenon can be observed through various stages of color changes as the temperature rises.

Explanation:
When the temperature of a substance is gradually increased, it goes through a series of color changes. These color changes can be summarized as follows:

1. Red: At lower temperatures, the substance may appear red. This is because the lower energy photons emitted by the heated substance have longer wavelengths, which correspond to the red region of the visible spectrum.

2. Yellow: As the temperature increases, the substance may appear yellow. This is due to the emission of higher energy photons with shorter wavelengths, which correspond to the yellow region of the visible spectrum.

3. Green: Further increase in temperature may cause the substance to appear green. This is because the emitted photons now have even higher energy and shorter wavelengths, corresponding to the green region of the visible spectrum.

4. White: Finally, as the temperature continues to rise, the substance appears white. White light is a combination of all colors in the visible spectrum. At high temperatures, the substance emits photons with a wide range of energies and wavelengths, resulting in the perception of white light.

Therefore, as the temperature of a substance gradually increases, its color changes from red to yellow, then to green, and ultimately to white. This phenomenon can be observed in various heated objects, such as metal rods, incandescent light bulbs, or even stars.

In conclusion, the correct answer is option 'D' - white.

The correct answer is option 'C' - Lord Rippon.

Lord Rippon, whose full name was George Frederick Samuel Robinson, served as the Viceroy of India from 1880 to 1884. During his tenure, he introduced several significant reforms and policies aimed at modernizing and improving the governance of India. One such reform was the creation of the Indian Imperial Order of the Star of India, which was established in 1861 to honor Indian princes and rulers who had been loyal to the British Empire.

Under Lord Rippon's administration, the Indian Imperial Order of the Star of India underwent some changes. One of these changes was the appointment of Maharana of Chittor as the Grand Commander of the order. The Maharana of Chittor was the ruler of the princely state of Chittor, located in present-day Rajasthan, India. The title of Grand Commander of the Star of India (GCSI) was bestowed upon the Maharana as a recognition of his loyalty and service to the British Empire.

By conferring this title upon the Maharana of Chittor, Lord Rippon acknowledged his significance and contributions as a ruler. This title was not only a symbol of honor but also carried a certain level of prestige and authority. The Grand Commander of the Star of India (GCSI) was considered a prestigious position within the Indian Imperial Order of the Star of India hierarchy.

Lord Rippon's decision to bestow this title upon the Maharana of Chittor was a strategic move to strengthen the British Empire's relationship with the princely states. It aimed to foster loyalty and cooperation among the rulers and ensure their continued support for British rule in India.

In conclusion, Lord Rippon, the Viceroy of India from 1880 to 1884, titled the Maharana of Chittor as the Grand Commander of the Star of India (GCSI). This title was a recognition of the Maharana's loyalty and service to the British Empire and aimed to strengthen the relationship between the British and the princely states.

Sr. Davis is tall.

Explanation:
The correct answer is option A, "is".

In this sentence, "Sr. Davis" is the subject, and "tall" is the predicate adjective that describes the subject. The verb "is" is the linking verb that connects the subject to the predicate adjective.

The linking verb "is" is used with singular subjects, such as "Sr. Davis". When using a singular subject, we use the singular form of the verb, which is "is". So, the correct sentence is "Sr. Davis is tall."

Let's break down the sentence further:

Subject: Sr. Davis
Predicate Adjective: tall
Linking Verb: is

So, the sentence structure is:

Subject + Linking Verb + Predicate Adjective

The linking verb "is" is used to show a state of being or to describe the subject. In this case, it is used to describe the height of Sr. Davis.

To summarize, the correct form of the verb to use with the singular subject "Sr. Davis" is "is". Therefore, the correct sentence is "Sr. Davis is tall."

To complete the sentence, we need to use the correct form of the verb "to be" to match the subject "Tony & Jonathan."

- The subject of the sentence is "Tony & Jonathan," which is a plural subject since it refers to two people.
- When we have a plural subject, we use the plural form of the verb "to be," which is "are."
- So, the correct sentence would be "Tony & Jonathan are from Mexico."
Therefore, the correct answer is C: are.

The given sentence is: "The yellow box and the pink box____beautiful."
To determine the correct verb that should fill in the blank, we need to consider the subject of the sentence. In this case, the subject is "The yellow box and the pink box." Since the subject is plural (two boxes), we need to use a plural verb.

The correct answer is B:.
Explanation:
To determine the correct word to fill in the blank, we need to understand the subject-verb agreement in the sentence. Here, the subject is "sky" which is singular, so we need to use the singular form of the verb.
- The word "am" (option A) is the first person singular form of the verb "to be" and is used with the pronoun "I". It is not suitable in this context because the subject is "sky", not "I".
- The word "is" (option B) is the third person singular form of the verb "to be" and is used with singular subjects. It correctly completes the sentence.
- The word "it" (option C) is a pronoun that refers back to a singular noun and is used as the subject of the sentence. While it is grammatically correct, it does not complete the sentence.
- The word "are" (option D) is the plural form of the verb "to be" and is used with plural subjects. It is not suitable in this context because the subject is singular.
In conclusion, the correct word to fill in the blank is "is" (option B) as it agrees with the singular subject "sky".

To determine the correct verb form to complete the sentence, we need to identify the subject of the sentence. In this case, the subject is "Cecy, Daisy, and Yulissa".
The correct verb form to use with a plural subject like "Cecy, Daisy, and Yulissa" is "are". Therefore, the correct answer is B: are funny.
Here is the detailed solution in bullet point format:
- The subject of the sentence is "Cecy, Daisy, and Yulissa".
- When the subject is plural, the verb form should also be plural.
- The verb form "are" is the correct form to use with a plural subject.
- Therefore, the correct answer is B: "are" funny.

Ms. Smith's class is a collective noun that refers to a specific group of individuals (students) who are part of the class. When we talk about a single class, we use the singular verb form "is" to agree with the singular noun "class". Therefore, the correct answer is option 'A' - "is".

Explanation:
- Singular subject requires a singular verb
- Collective noun: Ms. Smith's class
- Rule: When the subject is a collective noun, we use the singular verb form to agree with the singular noun.

Example:
- Ms. Smith's class is small. (Correct)
- Ms. Smith's class are small. (Incorrect)

In the given sentence, the subject "Ms. Smith's class" is a collective noun because it refers to a group of students together as one unit. Since it represents a single unit, we use the singular verb form "is" to agree with the subject.

Using "are" would be incorrect because it is the plural form of the verb and does not agree with the singular noun "class". Similarly, "am" is the first-person singular form of the verb and does not apply to the subject "Ms. Smith's class".

In conclusion, the correct answer is option 'A' - "is".
