According to the kinetic-molecular theory, particles of matter
A decrease in a materials volume when its temperature decreases
An increase in a materials volume when temperature increases.
are in constant motion.
it gains heat from the hot water and expands.
slow down and move closer together
volume decreases and density increases.
The particles move faster and expand, then slow down and contract.
thermal expansion
Alex noticed that a metal door that sticks on hot days does not stick when it cools off at night. This is because the metal contracts as it cools. The reason for this is that, as the metal cools, the particles:
A decrease in a materials volume when its temperature decreases
An increase in a materials volume when temperature increases.
are in constant motion.
it gains heat from the hot water and expands.
slow down and move closer together
volume decreases and density increases.
The particles move faster and expand, then slow down and contract.
thermal expansion
A substance is heated up and then allowed to cool down. What happens to the particles during this time period?
A decrease in a materials volume when its temperature decreases
An increase in a materials volume when temperature increases.
are in constant motion.
it gains heat from the hot water and expands.
slow down and move closer together
volume decreases and density increases.
The particles move faster and expand, then slow down and contract.
thermal expansion
Many objects, such as train tracks and road joints, are specifically designed to allow extra space for

it gains heat from the hot water and expands.
slow down and move closer together
volume decreases and density increases.
The particles move faster and expand, then slow down and contract.
thermal expansion
The liquid in a thermometer rises when it is placed in the hot water because

The particles move faster and expand, then slow down and contract.
thermal expansion
When objects contract upon cooling
