A balloon at STP is heated.Which of the following statements about the relationship between volume and temperature is TRUE?
A) As temperature increases, the volume of a gas decreases.
B) The volume of a gas is unaffected by temperature changes.
C) The volume of a gas is affected by temperature changes, but it is not possible to predict how it is affected.
D) Increasing the temperature would make some of the gas escape from the balloon, decreasing the volume.
E) As temperature increases, the volume of a gas also increases.

According to Charles's Law, the volume of a gas is directly proportional to its temperature when pressure is held constant. Therefore, if the temperature of a gas increases, its volume also increases, assuming the pressure and the amount of gas remain constant.
