Amplify Thermal Energy Review

Molecules in a hotter sample will....

• have more kinetic energy

• be moving faster

• be moving slower

• be red in color

There will always be heat transfer between two objects that are touching if...

• the temperatures are the same in each sample

• there is a difference in temperature between samples

When will heat transfer stop?

• When the molecules reach a state of equilibrium

• When the molecules are moving at the same speed

• When the kinetic energy is equal

• When there is a phase change from liquid to gas

When hot and cold air make contact with each other...

• the hot air will lose kinetic energy

• cold air will lose kinetic energy

How do air conditioners cool the air?

• Air conditioners cool air by air slowing molecules down.

• Air conditioners cool air by speeding air molecules up.

• Reaching Equilibrium at the same time

• Creating hot air instead of cold air

Imagine that your Mom just put a frozen Bubba-Burger on the hot grill to sizzle? In energy terms what is happening?

• The Bubba-Burger molecules are transferring energy to the grill

• The Bubba-Burger is at equilibrium with the grill

• The grill molecules are transferring energy to the Bubba-Burger

• The grill is creating energy with the Bubba-Burger

When two things are in contact, kinetic energy transfers...

• from slow-moving molecules to faster-moving molecules.

• from fast-moving molecules to slower-moving molecules.

• between the two things.

• nowhere and disappears
