Amplify Thermal Energy Test

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object due to their motion and position. It is related to temperature and heat.

Front

What happens to molecules at absolute zero?

Back

At absolute zero, the molecules of a sample would not be moving at all.

Front

How does temperature relate to molecular speed?

Back

As the speed of molecules increases, the temperature of the sample also increases.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transferred or transformed.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the molecules.

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) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat, without the need for a medium.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is specific heat capacity?

Back

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