You put a sealed container in the freezer while it is warm. Later when you look, the sides of the container are sucked in. Why?

• The  molecules in the container are moving slower as energy from the freezer is transferred to them, so the particles in the container move faster and the volume increases

• The  molecules in the container are moving slower as energy from the freezer is transferred to them, so the particles in the container move slower and the volume decreases

• The  molecules in the container are moving faster as energy from them is transferred to the freezer, so the particles in the container move faster and the volume increases

• The  molecules in the container are moving slower as energy from them is transferred to the freezer, so the particles in the container move slower and the volume decreases
