P down so T ?
The entire volume of a balloon is filled with air. However, over time, the balloon becomes soft as the air pressure inside it decreases.
According to the gas laws, which answer choice best describes the cause for the decrease in the balloon's air pressure?
a.The temperature of the air within the balloon increased, which caused the air particles to speed up and move farther apart.
b.The temperature of the air within the balloon decreased, which caused the air particles to slow down and move closer together.
c.The volume of the air within the balloon decreased, which caused the air particles to become cooler and slow down.
d.The volume of the air within the balloon increased, which caused the air particles to become warmer and speed up.
