Answer:
HEY MATE
(1)Temperature has a direct effect on whether a substance exists as a solid, liquid or gas. Generally, increasing the temperature turns solids into liquids and liquids into gases; reducing it turns gases into liquids and liquids into solids.
(2)Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
(3)By increasing the pressure, the air can be compressed. The compressed air is allowed to cool by decreasing its temperature and the air gets liquefied. The liquefied air is allowed to pass into a fractional distillation column. Depending upon their boiling point different gases get separated at different heights.
