Why do molecules change speed?

• Molecules change speed when they are at equilibrium

• Molecules speed up when they get energy from other molecules

• Sample A is hotter then sample B

• Molecules slow down when they give energy to other molecules

Raven cooked a pot of soup, then put half the soup in the freezer for a while. Now the soup in the pot is hot, and the soup in the freezer is cold. What is the difference between the molecules of the soup in the pot and the molecules of the soup in the freezer

• The molecules of the soup in the freezer are smaller than the molecules of the soup in the pot.

• There is no difference because all of the soup is made of the same type of molecules.

• The molecules of the soup in the pot are moving faster than the molecules of the soup in the freezer.

• The molecules of the soup in the pot are moving and the molecules of the soup in the freezer are not moving.

If a 40 and a 90 degree cup of coffee sit out on a 30 degree day, which cup will likely be warmest after 10 minutes?

• The 90 degree cup becasue it transferred energy to the colder air

• The 90 degree cup because it got energy from the colder air

• The 40 degree cup because it got energy from the colder air

• The 40 degree cup because it transferred energy to the colder air
