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.
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.
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.
Liquid
change of a liquid to a solid
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
