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 specific heat?

Back

Specific heat 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 (q)?

Back

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

Front

What is the unit of specific heat?

Back

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

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 is the symbol for heat?

Back

The symbol for heat is 'q'.

Front

How do you convert kilojoules to joules?

Back

To convert kilojoules to joules, multiply by 1000 (1 kJ = 1000 J).

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?

Back

Temperature is a measure of the average kinetic energy of particles, while heat is the energy transferred due to temperature difference.
