Test: Transmission of Heat, Light Electromagnetic Radiation - Question 1

Which mode of heat transmission primarily occurs in liquids and gases?

Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 1
Convection is the mode of heat transmission that primarily occurs in liquids and gases. In this process, heated particles move, creating convection currents that distribute heat throughout the substance. This is why convection is responsible for phenomena like ocean currents and the circulation of air in heating systems.
Test: Transmission of Heat, Light Electromagnetic Radiation - Question 2

What type of clothing is most suitable for staying cool in hot weather?

Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 2
White or light-colored clothes are more suitable for staying cool in hot weather because they absorb very little of the sun's heat, helping to keep the body cool. In contrast, black or dark-colored clothes absorb more heat and can make you feel warmer.

Test: Transmission of Heat, Light Electromagnetic Radiation - Question 3

Which law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another?

Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 3
The First Law of Thermodynamics, often referred to as the law of conservation of energy, states that energy cannot be created or destroyed but can only change from one form to another. It is a fundamental principle in thermodynamics.
Test: Transmission of Heat, Light Electromagnetic Radiation - Question 4
What type of electromagnetic waves are used for radar?
Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 4
Radar (Radio Detection and Ranging) uses high-frequency radio waves for detecting objects like ships and airplanes. These radio waves are emitted by a rotating aerial and reflected from objects, helping determine their distance.
Test: Transmission of Heat, Light Electromagnetic Radiation - Question 5
What is the purpose of a thermos flask's double-walled construction with a vacuum between the walls?
Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 5
A thermos flask's double-walled construction with a vacuum between the walls serves to prevent heat loss by radiation. The vacuum acts as an insulator, reducing the transfer of heat from the inside to the outside or vice versa.
Test: Transmission of Heat, Light Electromagnetic Radiation - Question 6
In a pressure cooker, why does water boil at a higher temperature than 100°C?
Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 6
In a pressure cooker, water boils at a higher temperature than 100°C because of the increased atmospheric pressure inside the cooker. This increased pressure allows the water to reach a higher boiling point, which speeds up the cooking process.
Test: Transmission of Heat, Light Electromagnetic Radiation - Question 7
Which type of refrigerant should have a large heat of evaporation?
Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 7
A refrigerant used in compression type refrigeration should have a large heat of evaporation. This property allows it to absorb heat efficiently during the evaporation process, contributing to the cooling effect in the system.
Test: Transmission of Heat, Light Electromagnetic Radiation - Question 8
What is the purpose of a greenhouse in horticulture?
Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 8
A greenhouse in horticulture is designed to trap heat and create a warm environment for plants. This helps extend the growing season, promote plant growth, and protect plants from adverse weather conditions.
Test: Transmission of Heat, Light Electromagnetic Radiation - Question 9
Which law of thermodynamics states that heat can only be transferred from a hot body to a cold body with the involvement of some work?
Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 9
The Second Law of Thermodynamics states that heat can only be transferred from a hot body to a cold body if some work is done. It sets limitations on the direction of heat transfer and is a fundamental principle in thermodynamics.
Test: Transmission of Heat, Light Electromagnetic Radiation - Question 10
What is the primary mode of heat transmission that occurs in solids?
Detailed Solution for Test: Transmission of Heat, Light Electromagnetic Radiation - Question 10
Conduction is the primary mode of heat transmission that occurs in solids. It involves the transfer of heat from particle to particle within a solid material without the particles themselves moving. Solids like metals are good conductors of heat.
