If we want to change the state of matter then we have to apply some pressure and temperature. Can we change the state of matter by applying only pressure or by changing only temperature or both pressure and temperature are needed to change the state of matter. Explain?

Answer:
Matter changes from one state to another by change in temperature and pressure. For e.g. solids on heating changes to liquid, liquid on further heating changes to gases. In same manner gases on compression means on applying pressure changes to liquid again.

Answer:
In some cases only temperature is needed and in some cases pressure and temperature both are needed simultaneously .
Like if we want to change ice to gas we only need to increase its temperature .
But if we want to condense a atmospheric gas we have to both decrease temperature and increase pressure .
