You took a balloon outside on a very cold day. You waited observed the balloon began to shrink. What is the best explanation of this?

• As the particles became cooler, they lost energy and moved less, resulting in less pressure on the balloon.

• As the particles became cooler, they gained energy and moved less, resulting in less pressure on the balloon.

• As the particles became cooler, they lost energy and moved less, resulting in more pressure on the balloon.

• As the particles became cooler, they gained energy and moved less, resulting in more pressure on the balloon.
