yes. Matter can change state when thermal energy is absorbed or released.
the law of conservation
Yes, it is true.
Condensation
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....
No. Rather released. As during the physical changes in the states of matter, there is breaking of bonds involved. Whenever bonds are broken, the atoms of that matter come closer and energy they give out is more as compared to energy taken while breaking bonds. Hence, Physical changes at the level of states of Matter are always Exothermic i.e. RELEASING HEAT.
A physical change occurs.
A 'phase' change.
yes it can be absorbed
It's thermal energy my dear.
Example for light energy is absorbed or released, Heat is released and absorbed, electrical energy absorbed or released...

Energy can be released when matter changes. For example when something burns, such as natural gas (methane) combining with oxygen from the air, such as happens in a gas stove, to form carbon dioxide and water and release lots of energy. If you use a gas stove, this is how you cook. Energy can be absorbed when matter changes. For example, when ice in your glass absorbs heat from the room and melts, a phase change from ice to water, energy is absorbed. Matter can change without either net absorption or net release of energy, but some energy may be borrowed to enable the change and then returned after the change.

When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
