Unit 2 Post Test Review

Front

What happens to the spacing between particles when heat is added?

Back

The spacing between particles increases.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two or more objects reach the same temperature and no heat flows between them.

Front

What are the three states of matter?

Back

Solid, Liquid, Gas.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves.

Front

How does temperature relate to kinetic energy?

Back

The higher the temperature, the greater the kinetic energy of the particles.

Front

What is the formula for calculating thermal energy?

Back

Thermal energy = mass × specific heat capacity × change in temperature.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of a substance by 1°C.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.
