In general: expanding while melting; except for ice to liquid water, this volume is shrinking!
Usually, yes. Most of the time the solid form is denser and therefore occupies a smaller volume than the liquid, but for a few substances the reverse is true.
Volume increases, and there is a change of phase from liquid to solid.
A gas will undergo a change in volume more easily than either a liquid or a solid.
The water in ice has a larger volume that water in its liquid form. That is why Ice floats. Ice is less dense than liquid water.
Liquid
A solid has a fixed volume and form. A liquid has a fixed volume but has the form of a container. A gas has not a fixed volume or form.
change of a liquid to a solid
The type of matter that has a definite shape but no definite volume is a solid. Solids have a fixed shape because their particles are closely packed together, but they can change volume slightly in response to temperature and pressure changes.
The change from liquid to solid is called freezing.
A state of matter that will not change shape or volume when moved to a different container is a solid. Solids have a fixed shape and volume because their particles are tightly packed and have very little freedom of movement.
Sure, change from solid to liquid is a physical change
when ice was solid change liquid because sun was very hot. ice will change liquid change back solid again
