How do you increase the motion of a water molecule?
You add heat
You remove heat
You drink it
You can't; it already has the greatest motion of all states of matter
Describe the motion of the molecules in a solid object.
It is not moving at all.
They are vibrating in place.
It is impossible to describe the motion of a solid object.
They are moving very quickly and they bounce and fly around inside the object.
Is there a relation ship between kinetic energy and temperature?
Yes, as the temperature increases, the kinetic energy increases.
Yes, as the temperature increases, the kinetic energy decreases.
No, there is not.
