Thermochemistry

Front

What is an exothermic process?

Back

An exothermic process is a chemical reaction or physical change that releases heat to the surroundings.

Front

What is an endothermic process?

Back

An endothermic process is a chemical reaction or physical change that absorbs heat from the surroundings.

Front

What is energy in the context of thermochemistry?

Back

Energy is the capacity to do work or supply heat.

Front

What is a calorimeter?

Back

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

Front

What is specific heat?

Back

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

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 the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the role of heat in chemical reactions?

Back

Heat can either be absorbed or released during chemical reactions, influencing the reaction's direction and rate.

Front

What is the significance of the heat of reaction?

Back

The heat of reaction is the amount of heat absorbed or released during a chemical reaction at constant pressure.

Front

What is a thermochemical equation?

Back

A thermochemical equation is a balanced chemical equation that includes the enthalpy change of the reaction.
