Which law states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other?

• Zeroth Law of Thermodynamics

• Second Law of Thermodynamics

• Third Law of Thermodynamics

• First Law of Thermodynamics

This diagram shows particles cooling from 10 K to 0K.

What will occur at 0K?

• Particles stop moving.

• Entropy increases.

• Particles increase Kinetic Energy.

Temperature is shown decreasing to 0K.

Which law of Thermodynamics is represented?

• Zeroth

• First

• Second

• Third

The temperature shown on the second block is 0K.

What is this temperature also known as?

• Freezing point

• Absolute zero

• Kinetic zero

The table is currently at room temperature.

After a few hours on the table, the hot coffee and the cold water will:

• Both heat up.

• Both cool down.

• Both be the same table as the table.
