Particles in a bowl of hot soup are moving _____ the particles in the soup when it has cooled.
the same speed as
slower than
faster than
particles do not move
A balloon expands when heat is applied to it. Why is this?
the gas cools off and causes the size of the balloon to change
when the gas heats up, the particles move closer together
when a gas is heated, the particles move faster and further away from each other, hitting the walls of the container with great force
when the gas cools, the particles move closer together
