Test: Time & Temperature - 2 - Class 5 MCQ

6:30 PM can be converted to the 24-hour clock format as follows:

• To convert to 24-hour time, add 12 to the hour for times in the PM.
• Thus, 6:30 PM becomes 18:30 hours.

250 minutes = 240 minutes + 10 minutes = 4 hours 10 minutes

To convert Fahrenheit to Celsius, use the following formula:

Subtract 32 from the Fahrenheit temperature.

Multiply the result by 5/9.

For 95°F:

Subtract 32: 95 - 32 = 63

Multiply by 5/9: 63 × 5/9 = 35°C

Therefore, 95°F is equal to 35°C.

To calculate the boiling point of water in Fahrenheit, we use the conversion formula from Celsius to Fahrenheit:

F=(C×9/5)+32

Where:C is the temperature in Celsius (100°C for boiling water), F is the temperature in Fahrenheit.

Step-by-Step Calculation:

1.Multiply the Celsius temperature by 9/5

100×9/5=180

2. Add 32 to the result:

180+32=212
So the answer is  212°F

To convert from Celsius to Fahrenheit, use the formula:

Multiply the Celsius temperature by 9/5.

Add 32 to the result.

For 25°C, the calculation is:

25 × 9/5 + 32 = 77°F

Thus, 25°C equals 77°F.

The increase in temperature can be calculated simply by subtracting the initial temperature from the final temperature.

• Initial Temperature: 20°C
• Final Temperature: 35°C
• Calculation: 35°C - 20°C
• Result: 15°C

Thus, the increase in temperature is 15°C.

To find the freezing point of water in Fahrenheit, use the conversion formula from Celsius:
Formula: F = (C × 9/5) + 32

C is the temperature in Celsius (0°C for freezing water).

F is the temperature in Fahrenheit.

Step-by-Step Calculation:

• Multiply the Celsius temperature by 9/5: 0 × 9/5 = 0
• Add 32 to the result: 0 + 32 = 32

 The freezing point of water in Fahrenheit is 32°F.
