Thermal Energy Flashcard

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

What happens to temperature during an endothermic process?

Back

The temperature of the surroundings decreases during an endothermic process.

Front

What happens to temperature during an exothermic process?

Back

The temperature of the surroundings increases during an exothermic process.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

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 the significance of the temperature difference in heat flow?

Back

Heat flows spontaneously from a region of higher temperature to a region of lower temperature.

Front

What is the role of a calorimeter?

Back

A calorimeter is a device used to measure the amount of heat involved in a chemical reaction or physical change.

Front

What is the specific heat capacity?

Back

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