Understanding 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.

Front

Why is a coffee cup used in calorimetry experiments?

Back

It acts as a good insulator.

Front

What does the heat absorbed by the water represent in a calorimetry experiment?

Back

The heat released by the metal.

Front

What is the equation for calculating specific heat?

Back

q = mcΔT.

Front

How is specific heat different from heat capacity?

Back

Specific heat is the energy required to raise 1 gram of a substance by 1°C.

Front

What is the specific heat of water?

Back

4.18 J/g°C.

Front

If you have 20 g of water with a specific heat of 4.18 J/g°C, how much heat energy is lost when the temperature changes from 25°C to 20°C?

Back

418 Joules.

Front

What does 'q' represent in the specific heat equation?

Back

'q' represents the heat energy absorbed or released.

Front

What is the unit of specific heat?

Back

Joules per gram per degree Celsius (J/g°C).

Front

What factors affect the amount of heat absorbed or released by a substance?

Back

Mass, specific heat, and temperature change.
