B). multiply, increase, fluctuates.
C). stay the same, increase, expand. Eliminate.
D). speed up, decrease, stay the same.

Answer 1

When the temperature is cold, Tim's tires look under-inflated. This is because the air molecules in the tire slow down causing their kinetic energy to decrease and volume to contract. slow down, decrease, contract on USA Test Prep its A.

Answer 2

The correct answer should be D). speed up, decrease, stay the same.

During cold times, air molecules speed up while the energy decreases. Since the volume stays the same, it appears as if the tires look under-inflated, while in reality they're not.
