An increase of decrease in the amount of energy within that substance initiates the state change. For example the heat of fusion from ice to water is 334kj/kg which means if i have 1kg of ice at 0 degrees Celsius (or -32 Fahrenheit) I have to add 334kj of energy to it in order to change it to 1kg of water at 0 degrees.

How can heat change things?
it can change them between states of Matter: Gas,Liquid,Solid and it can make the materials particles move faster (higher temperature).
What is needed for matter to change states?
heat energy
Does the weight of an object change when it changes states of matter?
Provided all of the matter is accounted for, then no.
When will matter undergo a change of states?

Does a substance change mass if it changes physically?
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
What is the difference between states of matter and change of state?
change of state is when the different states of matter are changed into one another. states of matter are gas, liquid, plasma and solid.
Can matter change states after a physical change?
Yes, matter can change states after a physical change.
Which of the states of matter have mass and volume?
No. Volume can change drastically between different states of matter, especially between solid and gas.
Is evaporation a change between which two states of matter?
Evaporation is a change from liquid water to a water vapour.
Can matter change states after a chemical change?
Yes it can.

What changes in states of matter?
chemical change
When the states of matter change to solid to liquid what is it called?
Physical change
When temperatures change almost all matter change states?
True
What is needed for matter to change states?
heat energy
Do all liquids change states of matter?
yes
