Question

how does temperatures change during change of physical state?​

Answer 1

Answer:

Temperature Change During Phase Change

Explanation:

Heat leaves the liquid as it freezes. Heat goes into the liquid as it vaporizes. Heat leaves the gas as it condenses. Heat goes into the solid as it sublimates.

The term 'change of phase' means the same thing as the term 'change of state'.

There are four states, or phases, of matter:

1. Solid
2. Liquid
3. Gas
4. Plasma

We will not be discussing the plasma state here.

When a substance changes from one state, or phase, of matter to another we say that it has undergone a change of state, or we say that it has undergone a change of phase. For example, ice melts and becomes water; water evaporates and becomes water vapor.

These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not.
