Specific Heat & Calorimetry

Front

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

Back

The particles speed up.

Front

What is the term for the amount of energy required to raise the temperature of 1 kg of a substance by 1ºC?

Back

Specific Heat.

Front

Which material would have the largest change in temperature when heated with the same amount of energy?

Back

The material with the lowest specific heat.

Front

What does temperature measure in terms of particle motion?

Back

Kinetic Energy.

Front

If you add the same amount of energy to two different volumes of water, which will have a greater temperature change?

Back

The smaller volume of water.

Front

Define specific heat capacity.

Back

The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is calorimetry?

Back

The science of measuring the heat of chemical reactions or physical changes.

Front

How does the specific heat of water compare to metals?

Back

Water has a higher specific heat than most metals, meaning it requires more energy to change its temperature.

Front

What is the formula for calculating heat energy?

Back

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

Front

What is thermal equilibrium?

Back

The state in which two bodies in contact with each other exchange no heat energy.
