Which of the following best explains why the volume of an inflated balloon
decreases when placed in a cold water bath? *
The balloon fills with water from the hot water bath.
As temperature decreases, the gas molecules move slower and the volume
decreases.
Higher temperatures cause a decrease in the pressure of the balloon.
The water cools down as the volume of the balloon increases.
