Chapter 4.2 Flashcard - Heat

Front

What happens if two objects that are touching have the same temperature?

Back

No heat transfer occurs between them.

Front

Thermal energy or heat energy

Back

Thermal energy is the total kinetic energy of particles in a substance

Front

If you have two identical objects, one is heated up and the other is cooled, which one will have a lower density because they have a larger volume?

Back

The heated object will have a lower density.

Front

Which type of heat transfer can travel through space?

Back

Radiation

Front

Which type of heat transfer can only be done by direct contact of particles? Options: Convection, Radiation, Evaporation, Conduction

Back

Conduction

Front

Conductor

Back

A conductor is a material that facilitates or helps the flow of heat.

Front

If an object has a high specific heat, what does that mean?

Back

It can absorb a lot of heat without a significant temperature change.

Front

If an object has low specific heat, what does that mean?

Back

It means the object heats up and cools down quickly.

Front

Which direction is heat flowing in the picture?

Back

from the hand to the ice

Front

Thermal energy always moves:

Back

From a high temperature object to a lower temperature object.
