### Heat is NOT transferred by

• A.

Conduction

• B.

Composition

• C.

• D.

Convection

B. Composition
Explanation
Heat is not transferred by composition. Composition refers to the arrangement and types of particles in a substance. While composition can affect the ability of a material to conduct or transfer heat, it is not a direct method of heat transfer. Conduction, radiation, and convection are the three primary methods of heat transfer. Conduction involves the transfer of heat through direct contact between particles, radiation is the transfer of heat through electromagnetic waves, and convection is the transfer of heat through the movement of fluids.

### If you touch something and it feels hot, then you are feeling heat by

• A.

Conduction

• B.

• C.

Convection

• D.

Beyonce

A. Conduction
Explanation
Conduction is the transfer of heat through direct contact between two objects or substances. When you touch something and it feels hot, it means that heat is being transferred from the object to your hand through conduction. The molecules in the object vibrate and transfer their kinetic energy to the molecules in your hand, causing the sensation of heat. Radiation refers to the transfer of heat through electromagnetic waves, while convection involves the transfer of heat through the movement of fluids. Beyonce is not related to the transfer of heat in this context.

### Light from the sun or an overhead light is an example of

• A.

Conduction

• B.

• C.

Convection

• D.

Explanation
Light from the sun or an overhead light is an example of radiation because radiation is the transfer of energy through electromagnetic waves. In this case, the light energy is emitted from the source (sun or light bulb) and travels through space or air to reach our eyes. This transfer of energy does not require a medium to travel through, unlike conduction or convection which require a physical substance. Therefore, radiation is the most suitable explanation for the given scenario.

### Steam, hot air and smoke are examples of

• A.

Conduction

• B.

• C.

Convection

C. Convection
Explanation
Steam, hot air, and smoke are examples of convection because convection is the transfer of heat through the movement of a fluid or gas. In this case, the fluid or gas is the steam, hot air, and smoke. Convection occurs when the fluid or gas is heated, becomes less dense, and rises, carrying the heat energy with it. This creates a continuous cycle of rising and falling, transferring heat from one place to another. Therefore, steam, hot air, and smoke are all examples of convection.

### Closing of doors, windows and hatches is one way to stop the spread of heat by

• A.

Conduction

• B.

• C.

Convection

A. Conduction
Explanation
Closing doors, windows, and hatches prevents the spread of heat by conduction. Conduction is the transfer of heat through direct contact between objects or substances. When doors, windows, and hatches are closed, they create a barrier that limits the transfer of heat from one area to another. This restricts the flow of heat through solid materials, such as walls and floors, reducing the overall spread of heat.
