Amplify Thermal Energy Chapter 2 Review

Front

What is temperature?

Back

Temperature is the measure of the average kinetic energy of the molecules of a substance.

Front

What happens to molecules at absolute zero?

Back

At absolute zero, the molecules would not be moving at all.

Front

Which temperature is warmer: 10℃ or 75℃?

Back

75℃ is warmer than 10℃.

Front

Which temperature is colder: 10℃ or 70℃?

Back

10℃ is colder than 70℃.

Front

What is the warmest temperature among 10℃, 25℃, 70℃, and 75℃?

Back

75℃ is the warmest temperature.

Front

What is the coldest temperature among 10℃, 25℃, 70℃, and 75℃?

Back

10℃ is the coldest temperature.

Front

In a thermal system, what does it mean if two samples do not change when they come into contact?

Back

It means that the two samples are in thermal equilibrium.

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.

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

How does temperature relate to molecular motion?

Back

Higher temperatures indicate faster molecular motion, while lower temperatures indicate slower molecular motion.
