If you fill up a balloon with a small amount of air, then set it in direct sunlight, you will see that the balloon expands. This expansion is due to an increase in volume, which results from an increase in the temperature of the air in the balloon.
This increase in temperature increases the ______________ of the gas, which results in the gas particles moving faster and colliding more often with the wall of the container. These collisions are what increase the pressure of the gas on the balloon, and ultimately cause the balloon to stretch out.
