Heat, Temperature, and Thermal Energy

Front

What is thermal energy?

Back

The sum of the kinetic energy and the potential energy of the particles that make up an object.

Front

Which cup has the most thermal energy if all cups have the same temperature?

Back

The large cup (Trenta) has the most thermal energy because it contains more cocoa.

Front

What is heat?

Back

The movement of thermal energy from a warmer object to a cooler object.

Front

What causes heat transfer between objects?

Back

A difference in temperature.

Front

What is temperature?

Back

The average kinetic energy of the particles that make up a substance.

Front

How does the size of an object affect its thermal energy?

Back

Larger objects can have more thermal energy if they have the same temperature as smaller objects.

Front

What happens to thermal energy when ice melts?

Back

Thermal energy is absorbed by the ice, causing it to change from solid to liquid.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

The transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

The transfer of thermal energy through electromagnetic waves, such as sunlight.
