Heat, Temperature, and Thermal Energy

Front

What happens to heat when two objects have different temperatures?

Back

Heat flows from the warmer object to the cooler one until they both have an equal temperature.

Front

What is temperature?

Back

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

Front

Why does a hot iron cool down when turned off?

Back

The iron cools because heat energy is transferred from the warm iron to the cooler room.

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

Heat is thermal energy transferred from one object to another because of a difference in temperature.

Front

What is thermal energy?

Back

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

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What occurs during conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is the effect of mass on thermal energy?

Back

The more mass an object has, the more thermal energy it can store at a given temperature.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred due to temperature difference, while temperature measures the average kinetic energy of particles.
