Heat Transfer

What is convection?

• A type of dance movement

• A type of rock formation

• A method of preserving food

• Transfer of heat through the movement of a fluid

Give an example of conduction.

• Metal spoon in a hot cup of coffee

• Plastic spoon in a hot cup of coffee

• Wooden spoon in a hot cup of coffee

• Glass spoon in a hot cup of coffee

Explain how radiation works.

• Radiation works by reducing the risk of cancer development in cells.

• Radiation works by improving the immune system's response to infections.

• Radiation works by damaging the DNA in cells, which can lead to cell death or mutations.

• Radiation works by increasing the production of healthy cells in the body.

How does heat move in convection?

• Heat moves in convection through the absence of fluid or gas

• Heat moves in convection through the movement of fluid or gas particles.

• Heat moves in convection through the solid particles

• Heat moves in convection through the process of radiation

What type of heat transfer occurs when you touch a hot pan?

• Conduction

• Convection

• Radiation

• Insulation

What is the main source of radiation on Earth?

• The Sun

• Lightning

• Volcanoes

• The Moon

What happens to the particles in a substance when it is heated by conduction?

• The particles in the substance gain kinetic energy and vibrate more rapidly, causing the substance to expand.

• The particles in the substance transform into a different state of matter when heated.

• The particles in the substance remain stationary and do not react to the heat.

• The particles in the substance lose kinetic energy and slow down, causing the substance to contract.

What type of heat transfer occurs when you feel the warmth of the sun?

• Conduction

• Radiation

• Insulation

• Convection

What is the role of fluids in convection?

• Fluids have no impact on the transfer of heat through convection.

• Fluids facilitate the transfer of heat through the movement of the fluid, creating a continuous cycle of heat transfer.

• Fluids inhibit the transfer of heat through the movement of the fluid, disrupting the cycle of heat transfer.

• Fluids only transfer heat through radiation, not convection.

How does conduction occur in solids?

• Conduction in solids occurs through the transfer of sound waves between particles

• Conduction in solids occurs through the emission of light particles

• Conduction in solids occurs through the movement of electrons between particles

• Conduction in solids occurs through the transfer of kinetic energy from one particle to another within the material.
