What is the effect of pressure on 3 state of matter? |
| Answer» The physical state of matter can be changed by changing the pressure. By lowering temperature and increasing the pressure gases can be changed into liquids and some solids can be changed into gases on decreasing the pressure. This happens with gases as there is lots of space between the particles of a gas and upon applying high pressure particles come close to each other which upon cooling gets liquified.\tIf the pressure above a liquid is increased sufficiently, the liquid forms a solid.\tIf the pressure above a liquid is decreased sufficiently, the liquid forms a gas. | |
