Calorimetry Practice

Front

What is calorimetry?

Back

Calorimetry is the science of measuring the amount of heat absorbed or released during a chemical reaction or physical change.

Front

What is the principle of conservation of energy in calorimetry?

Back

The principle states that energy cannot be created or destroyed, only transformed from one form to another, meaning the total energy in a closed system remains constant.

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 specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

What is the formula for calculating heat transfer?

Back

Q = mcΔT, where Q is the heat transfer, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.

Front

What happens to energy when ice melts?

Back

When ice melts, it absorbs energy from its surroundings, which is used to break the bonds between the ice molecules.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.

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 unit of specific heat capacity?

Back

The unit of specific heat capacity is Joules per gram per degree Celsius (J/g°C).

Front

What is latent heat?

Back

Latent heat is the amount of heat required to change the state of a substance without changing its temperature.
