Calorimetry

Front

What is calorimetry?

Back

Calorimetry is the science of measuring the heat of chemical reactions or physical changes, as well as heat capacity.

What happens to particles when heat is added to a substance?

Back

The particles speed up as they gain energy.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a substance.

Front

What is an exothermic process?

Back

An exothermic process is a reaction that releases energy, usually in the form of heat, to its surroundings.

Front

What does 'ΔT' represent in calorimetry?

Back

ΔT represents a change in temperature.

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 degree Celsius.

Front

What is the specific heat of water?

Back

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

Front

How do you calculate heat transfer (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 formula for calculating the specific heat of a substance?

Back

Specific heat (c) = q / (m × ΔT), where q is heat absorbed or released, m is mass, and ΔT is the change in temperature.

Front

What is the principle of conservation of energy in calorimetry?

Back

The principle states that energy cannot be created or destroyed, only transferred or transformed.
