Amplify Thermal Energy

Front

What happens to the molecules of a substance when the temperature increases?

Back

The energy of the molecules increases.

Front

What happens to the energy of a glass when iced tea is poured into it?

Back

The energy of the glass decreases while the energy of the iced tea increases.

Front

Do molecules move at the same speed regardless of temperature?

Back

False.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

From where does energy transfer occur?

Back

Energy will always be transferred from the hotter sample to the colder sample.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a substance.

Front

How does temperature relate to the energy of molecules?

Back

As temperature increases, the energy of the molecules increases.

Front

What is the relationship between heat and temperature?

Back

Heat is the transfer of thermal energy, while temperature measures the average kinetic energy of molecules.

Front

What happens to the motion of molecules in a solid when heated?

Back

The molecules vibrate faster as they gain energy.

Front

What is the effect of cooling on the energy of molecules?

Back

Cooling decreases the energy of the molecules.
