Freezing, condensation involves in cooling Melting, evaporation, boiling, sublimation, and the change from gas to plasma needs heating.
It hasn't for 20 years.
Maxwell's studies helped Wilhelm Roentgen discover energy waves that were capable of penetrating solid matter
I don't know. Why does it matter? I'm not a politician!
penetrating it
army orders are like rules but their serious and you have too folllow them no matter what you can easily get kicked out the army without following orders. army orders are like rules but their serious and you have too folllow them no matter what you can easily get kicked out the army without following orders.
Heating and cooling for instance.
Physical, or state changes are usually accomplished with heating or cooling
With the help of some physical and chemical processes matter changes its state. Like using heating , cooling etc we can change the state of matter,
Heating and cooling change the state of the matter. For example, at room temperature water is a liquid but if you heated it becomes steam; a gas. If you freeze it it becomes ice; a solid. Hope it helps xx
massWell, there are two measurements that I will give you because I am unsure of the question. Density is the number of particles in a material chunk. This doesn't change unless the form of the matter changes (like cooling or heating). Volume is the amount had at the moment. This changes.

plasma
That is done by either heating or cooling.
heating and cooling
By heating: transformation in a gas.By cooling: transformation in a solid.
You change one state of matter to another by heating the matter or cooling it [aka] adding energy or removing the energy
For example heating lead to melting and boiling - changes of matter phases.
