Thermodynamics Practice

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.

Front

Why is sand hotter than water at the beach?

Back

Sand has a lower specific heat than water, meaning it heats up faster.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through solids.

Front

How does thermal energy move between objects?

Back

Thermal energy always moves from a high temperature object to a lower temperature object.

Front

What unit is used to measure thermal energy?

Back

The unit used to measure thermal energy is Joules (J).

Front

Is copper a conductor or insulator?

Back

Copper is a conductor.

Front

What is convection?

Back

Convection is the transfer of thermal energy through liquids and gases.

Front

What is radiation in terms of thermal energy?

Back

Radiation is the transfer of thermal energy as electromagnetic waves.

Front

What happens to the temperature of a substance when it absorbs thermal energy?

Back

The temperature of the substance increases.

Front

What is the relationship between mass and thermal energy?

Back

The thermal energy of an object is directly proportional to its mass and temperature.
