Question 12 • Chemistry

The particles of a gas inside a balloon are experiencing an increase in their average kinetic energy and the number of collisions with the wall of the balloon. What is the most likely outcome?

Answer
A
a large increase in air temperature outside the balloon
B
higher air pressure outside the balloon
C
a decrease in gas temperature inside the balloon
D
higher gas pressure inside the balloon

Explanation

Average kinetic energy increases when the gas temperature increases. The faster-moving particles collide with the balloon’s walls more often and with greater force, so the gas pressure inside the balloon rises. Therefore, the most likely outcome is higher gas pressure inside the balloon.
