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 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 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

How do you calculate heat (q)?

Back

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

Front

What happens to temperature when kinetic energy increases?

Back

When kinetic energy increases, the temperature of the substance increases.

Front

What is the specific heat of water?

Back

The specific heat of water is 4.18 J/g°C.

Front

What is the formula for calculating heat released or absorbed?

Back

q = m × c × ΔT.

Front

What does the symbol 'q' represent in thermochemistry?

Back

In thermochemistry, 'q' represents the amount of heat energy.

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.
