Fundamentals Heat, Temp, Energy Transfer Review

Front

What is the definition of heat?

Back

Heat is the energy transferred between objects due to a temperature difference.

Front

What is temperature?

Back

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

Front

What is the standard unit of heat?

Back

The standard unit of heat is Joules (J) or calories.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What happens to heat transfer when two objects are at the same temperature?

Back

No heat transfer occurs between two objects at the same temperature.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects in contact have the same temperature and no heat flows between them.

Front

How does heat flow between two objects of different temperatures?

Back

Heat flows from the warmer object to the cooler object until they reach thermal equilibrium.

Front

What is the role of specific heat capacity?

Back

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