State of matter is referring to a substances existence as a solid, liquid, or gas. So, a common example would be solid water (we call it ice) changing state to liquid water due to the addition of energy (possibly heat). If energy continues to enter the system the liquid water will change state again to become a gas (steam).

Melting is an example of a?
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
What can occur when matter changes state?
when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....
Heat causes physical changes in matter by changing?
Typically heat changes the STATE of matter from solid to liquid to gas.However, heat can also cause chemical changes for example combustion.
How does heat change the state if matter?
For example heating lead to melting and boiling - changes of matter phases.
What is the process called when a solid changes to a gas?
Sublimation. It is a physical change, like all state changes. An example of a substance that does this is carbon dioxide (dry ice.)
Is evaporation of gasoline a example of physical change?
All changes of state are physical changes. Nothing happens to the molecules of gasoline when it evaporates, they just get further apart.
What are somethings in everyday life that changes state of matter?
The most simple example is water: gas, liquid or solid.
Is sublimation the way a balloon decreases in volume when the temperature is decreased?
No. Sublimation is when a solid changes it's state to a gas or when a gas changes it's state to a solid. Example : Dry ice (solid CO2) sublimates to gaseous CO2.
Are state changes physical or chemical changes?
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
Is Change of state is chemical or physical property?
No, a change of state is not a chemical change, for it can be changed back to its original form and their is no change in the molecular composition of the substance. A chemical change is when it cannot be changed back. The above example is an example of a physical change. Example:- ice when heated changes into water and water when cooled changes into ice.
How substances changes from one state to the other state?
through changes of energy
Why are changes of state chemical changes?
They aren't; a change of state is a physical change
