What is the average in mathematics?

Back

The average is a number that summarizes a set of data, computed by adding all the numbers in a list and dividing by the number of numbers.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of the molecules increases.

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature is a measure of the average kinetic energy of particles.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.
