Last summer vacation, the Cruz family decided to go to Pagudpod, Ilocos Norte to have a beach party. On their way to Ilocos, all of them were surprised when the tire suddenly exploded. What is the probable explanation for the blown-out tire during a long summer drive?

• High temperature causes a decrease in volume.

• The amount of the gases inside the tire is increased.

• The mass of the gases inside the tire increases causing a blown-up tire.

• The volume of gases increases as the temperature increases, causing a blown up tire.
