What are the similarities and differences between these two graphs?

Answer explanation

They both show the distribution of particles and kinetic energy. They have the same overall shape.

The hot sample is more flat, showing a higher value for the average kinetic energy. Meaning the temperature is hotter.

The cold sample is less flat, showing a lower value for the average kinetic energy. Meaning the temperature is colder.

The condition where two substances in physical contact with each other exchange no heat energy. They are said to be the same temperature.

• Thermal Energy

• Cooler to Warmer

• Energy Transfer

• Thermal Equilibrium

Two objects have different temperatures. Object A has a temperature of 42 degrees and Object B is 37 degrees. Which direction should the energy transfer between Objects A and B?

• From Object A to Object B

• From Object B to Object A

• Energy will not transfer

• Energy will transfer both directions

Choose the correct statement.

Please read carefully!!

• Energy can be created and destroyed. Therefore, as energy disappears, it goes in one part of the system as it jumps in another part of the system.

• Energy isn’t created or destroyed. Therefore, as energy transfers, it increases in one part of the system as it decreases in another part of the system.

An air conditioner uses machines and chemicals to remove kinetic energy from the molecules that make up the air inside a room. This _______ the molecules ______ and _______ the room’s air temperature.

• This slows the molecules down and lowers the room’s air temperature.

• This increases the molecules up and increases the room’s air temperature.
