Which is NOT a heat transfer by radiation?

• A bottle sitting in the sun that gets warm

• Sitting beside of a campfire and feeling the heat

• A pot of water heating over a hot stove

• A person sunbathing

A fireplace is heating an entire house through

• radiation

• conduction

• convection

Aluminum changes temperature at a slower pace than lead. Aluminum has a higher

• temperature

• conduction rate

• thermal energy

• specific heat

Roller coasters have gaps in the tracks so they can expand in hot weather due to

• thermal expansion

• specific heat

• mood swings

• thermal conductivity

Warming a marshmallow OVER a campfire is an example of

• radiation

• convection

• conduction

• global warming

When a gas or liquid heat up, what happens?

Mr. Salyer has a two-story house. In the winter, he uses his downstairs heating unit because the arm air

• contracts, rises, and heats the house through conduction

• expands, sinks, and heats the house through convection

• expands, rises, and heats the house through convection

When a stethoscope touches your skin, what happens?

• heat travels from the stethoscope to your skin
