Deformation occurs
because of change in its temperature
Matter changes state because of temperature and pressure. These quantities bring change.
The viscosity of a substance will change with both temperature and pressure. For liquids the changes induced by a change in temperature are usually more readily observed than the changes from pressure because liquids are only slightly compressible with pressure. In gasses, the changes in viscosity with pressure are much more easily demonstrated because gases are, almost by definition, quite compressible so that the density can be easily changed by either changes in pressure or changes in temperature.
Changes in temperature and pressure.
Change the pressure or change the temperature. Volume changes inversely with pressure and directly with temperature. That is to say, if you squeeze it, it gets smaller. If you heat it, it gets bigger.
how can changes in temperature and /or air pressure result in the formation of clouds
Pressure Temperature Changes in the molecular structure(chemical change)
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
Your question makes no sense. What substance changes from one state of matter to another (that is the first part and makes sense) at temperature and pressure experiencing earths surface? What on earth does that mean? pressure experiencing earths surface? What could it possibly mean? I really have no clue what you are trying to ask in the second part of the question. The first part however may give a clue to what you actually mean to ask. Maybe you mean "What substance changes from one state of matter to another at the temperature and pressure experienced on earths surface?" But using that as the question, there are literally hundreds or even thousands of correct answers. Here are a few Water, a liquid, changes to ice, a solid, and to steam, a gas and back to water Iodine can change from its solid form to a gas Ammonia can change from a liquid to a gas Freon can change from a liquid to a gas phosphorus can change from a solid to a gas gasoline, ether, liquid petroleum gas, naphtha, acetone, acetate all change from a liquid to a gas at atmosphere pressure at earths surface. Sodium changes from a solid to a gas. Hope this helps answer your question.
Volume ChangesThe volume of any solid, liquid, or gas will change with changes in temperature.
Because if those change the volume changes.
usually a change in temperature.... OR PRESSURE Which all mean a change in entropy of the system
