Explain how pressure and temperature determine the state of a substance
Answers
Answer:
On further increasing the temperature, the liquid state will convert into gaseous state. Similarly, when we increase pressure on a liquid substance or matter then the molecules start to come closer to each other. ... Also, when pressure is increased on a gas it will start to convert into liquid state.
Explanation:
Matter can exist in a solid, liquid or gaseous state, and the state a substance is in can be largely determined by its temperature. At low temperatures, molecular motion decreases and substances have less internal energy. A gaseous state exists when molecules have absorbed so much heat energy due to increased temperatures that they are free to move around one another at high speeds. A substance may undergo a phase change from a solid to a gas or from a gas to a solid if the temperature it is exposed to is changed in sudden. If pressure is constant, the state of a substance will depend entirely on the temperature it is exposed to substances
