Gas is much less dense than liquid.
yes it does
The density changes.
A LIQUID FREEZES TO SOLID
It depends on what material you have taken under consideration example, in case of water , when ice changes to water its density increases and decreases water turns into steam . So one has to actually experiment himself/herself to know what actually happens to the material under consideration. it will lessen>AOA
It melts
It becomes cold water
volume increses,
When water changes from a solid to a liquid, it undergoes melting. When it changes from a liquid to a vapor, it undergoes evaporation. These changes are driven by increases in temperature and energy levels.
It changes to gaseous state
If the density of a solid substance is more than that of a liquid, the solid substance will sink in the liquid. This is because objects with higher density will displace a volume of liquid that has a lower density, causing the solid to sink to the bottom.
You can't compress water when it is a liquid. That's why hydraulic systems work the way they do.
the ice expands the rock
