Amplify Thermal Energy Review

Front

What happens to the temperature of two samples when they achieve thermal equilibrium?

Back

The temperature of both samples will be the same, but it may not be 30 degrees.

Front

Do molecules move at the same speed regardless of temperature?

Back

No, molecules move faster at higher temperatures.

Front

How does energy transfer occur when two objects collide?

Back

Energy transfers from the warmer object to the cooler object.

Front

What is required for energy transfer to occur between two objects that are touching?

Back

There must be a difference in temperature between the two objects.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What is the relationship between temperature and molecular motion?

Back

As temperature increases, molecular motion increases.

Front

What occurs when two objects at different temperatures come into contact?

Back

Heat will flow from the hotter object to the cooler object until they reach equilibrium.
