How does the initial temperature and mass of a substance affect heat energy transfer?

Back

The greater the initial temperature and mass, the greater the transfer of heat energy.

Front

Define heat energy.

Back

Heat energy is the energy that comes from the temperature of matter; it is the energy that is transferred from one body to another due to a difference in temperature.

What is the relationship between temperature and particle movement?

Back

As temperature increases, the movement of particles increases.

What is a controlled variable in an experiment?

Back

A controlled variable is a factor that is kept constant to ensure that the results are due to the independent variable.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated by the experimenter.

Explain the concept of thermal equilibrium.

Back

Thermal equilibrium is the state in which two bodies in contact with each other exchange no heat energy, meaning they are at the same temperature.
