Thermal Energy Amplify Ch.1

Front

What is the average kinetic energy of the molecules in a sample?

Back

The average kinetic energy of the molecules in a sample is a measure of the temperature of that sample.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold something is.

Front

Which diagram shows the correct energy levels for hot and cold water?

Back

Diagram B shows the correct energy levels for hot and cold water.

Front

What is the average?

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 in the list.

Front

How do you determine which object is hotter?

Back

An object is hotter if it has the highest average kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What happens to the kinetic energy of molecules as temperature increases?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, including both kinetic and potential energy.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total energy of all particles.

Front

What is equilibrium in terms of thermal energy?

Back

Equilibrium occurs when two objects in contact reach the same temperature and no heat flows between them.
