Question

You have probably seen the heating curve of water. This graph represents a cooling curve of

another substance. You can see that over time, the temperature of the substance decreases
and the substance changes from a gas to a liquid to a solid. What other information do we know
about this substance as it changes?
nd kinetic energy

Answer 1

As the substance changes from a gas to a liquid to a solid, we know that its state of matter changes, and so does its density and kinetic energy.

* Density: As the substance transitions from a gas to a liquid, its density increases, and then decreases as it solidifies.

* Kinetic Energy: As the substance cools and condenses, its kinetic energy decreases, and when it reaches its melting point, its kinetic energy is at its lowest point.
