Question

how does matter change phases? matter changes from solid to liquid to gas with temperature increase and vice versa with temperature decrease. matter does not change phases under normal conditions. matter changes phases only when pressure is applied. matter changes from gas to liquid to solid with temperature increase.

Explanation:

Matter changes phase with temperature and pressure changes. Heating causes solid - liquid - gas transitions and cooling causes gas - liquid - solid transitions. Pressure also affects phase changes.

Answer:

A. Matter changes from solid to liquid to gas with temperature increase and vice versa with temperature decrease.
