If you add heat to matter, it can either get it hotter, or it can change the state of matter (for example, from solid to liquid).
A good example is the boiling kettle. When the water is boiling the water molucles jump about and some escape up the kettles spout. Most people will notice the water vapour first which mistakingly they call steam. The real steam is a few centimeters from the end of the spout and is invisible.
How does heat Change matter?
When applied it heats the matter up - increasing its energy content - in relation to its ability to hold the heat.
Depending on the material it can change state when it can hold no more energy, re liberating its stored energy. From a solid it would got to Liguid to a gas.
Most substances will expand when heated. -- So the volume becmes greater.
A physical change is a change in the form of matter but not the chemical composition of it.
Heat or cool it.
Heat is needed for matter to change form eg: Melting, condensation, etc.
please clarify your question.
Heat change and pressure change are the only reasons, but in our atmosphere, more often heat.
If you add heat to matter, it can either get it hotter, or it can change the state of matter (for example, from solid to liquid).
The change in which no new kinds of matter are formed but the size, shape or state of the matter may change is known as a physical change.
a change in size, shape or the state of matter is a physical change. True for A+.
IT IS PHYSICAL change
A physical change is a change in the form of matter but not the chemical composition of it.
size
heat energy
Heat or cool it.
Heat causes matter to become warmer, usually to expand,and occasionally to change its physical state.
By adding heat and removing heat.
mass doesn't change
one of them is the heat.
