Question

What is freezing and boiling point?

Answer 1

1. The temperature at which the vapour pressure of the liquid or any substance on being heated (or not) becomes equivalent to the atmospheric pressure or the pressure of the surroundings is known as the boiling point.
2. The boiling point is the property of pressure and not temperature. When the pressure of the surroundings changes, so does the boiling point of the liquid or substance.
3. The temperature at which liquid begins to solidify is known as the freezing point. It makes the liquid shows the properties of a solid, where the molecules come closer to each other.
4. The freezing point also depends on the pressure. As pressure increases so do the freezing point of the substance increases.
5. The freezing point is always less than the boiling point.
