A 65 degree sample makes contact with a 35 degree sample, how will the systems react?

• The red will get hotter along with the black

• The red will get hotter with energy from the black until they are equal

• The black will get colder with energy from red until they equal

• The black will share energy with the red forever

Why did the red food coloring mix faster than the blue food coloring?

• the red was in the hot water

• the red was in the cold water

• the blue was in the hot water

• the blue was in the cold water

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

Why does the transfer of energy between two colliding things stop?

• Molecules stop transferring energy when colliding systems reach equilibrium

• When the two non-colliding things get equally hot molecules make energy

• Molecules make more kinetic energy until it is balanced

• The molecules of a system destroy energy when the system is balanced
