Question

Zeke is on spring break. He lives in a cold climate, so he decides to drive to a warmer climate. Before he leaves for his vacation, he checks the air pressure in his tires. After a few days of driving, he reaches his destination and stops for more fuel. While fueling up, he checks his tires' air pressure again and notices it has increased.
Which option best explains the change in the air pressure of Zeke's tires? Select all that apply.

a. The warmer temperatures at Zeke's destination caused the volume of air in his tires to decrease.
b. The warmer temperatures at Zeke's destination caused the volume of air in his tires to increase.
c. The warmer temperatures at Zeke's destination caused the pressure in his tires to spread out equally.
d. The warmer temperatures at Zeke's destination caused the pressure in his tires to increase.

Answer 1

D.
This happens because in warmer temperatures, the atoms are more active. This increases the pressure because each atom uses up more space as they become more active.
