What happens when a substance changes state from a solid or liquid?
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.
What happens as more matter gets packed into same amount of space the material's density changes in what way?
it gets denser
What happens when a hydrogen atom changes from the excited state to the ground state?
It gives off a photon of energy.
Does changing the mass change the density?
Density never changes >.<
When matter changes its state what happens?
It either absorbs or releases an unexpectedly large quantity of energy.
What happens to water as it changes state?
The density changes.
What happens to the density if you change the volume?
it changes
If you have the same volume and the mass changes what happens to the density?
The density changes in direct proportion with the mass. A lesser mass results in a lesser density and a greater mass results in a greater density.

Which state of matter is least dense?
Which element changes the density of matter
What happens to the level of molecules as water cools?
Nothing they stay the same - their density changes.
What happens to the state of liquid water when it evaporates?
It changes to gaseous state
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
What happens to a substance during changing between a solid to a liquid?
When a substance changes from a solid to a liquid and vice versa, its density changes.
What happens during state of change?
Kinetic Energy is gained in the foward changes and lost in the reverse changes of state
What happens to the speed of light as it enters a different meduim?
It changes, in accordance with the optical density of the medium.
What changes over time with density?
density changes when the substance changes.
