Thermochemistry

Front

What is thermochemistry?

Back

Thermochemistry is the study of the heat energy associated with chemical reactions and changes of state.

Front

What is the 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°C.

Front

What is the formula for calculating heat energy?

Back

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

Front

What does an exothermic reaction do?

Back

An exothermic reaction releases heat energy to the surroundings.

Front

What does an endothermic reaction do?

Back

An endothermic reaction absorbs heat energy from the surroundings.

Front

What is the symbol for heat in thermodynamics?

Back

The symbol for heat is 'q'.

Front

What are the two main types of energy in thermochemistry?

Back

The two main types of energy are potential energy and kinetic energy.

Front

What is the heat of combustion?

Back

The heat of combustion is the amount of heat released when a substance is completely burned in oxygen.

Front

What is the relationship between temperature and heat energy?

Back

As temperature increases, the heat energy of a substance also increases.

Front

What is the unit of heat energy?

Back

The unit of heat energy is Joules (J).
