Question

(a) What are the two ways in which the physical states of matter can be changed? (b) Draw the &#x2018;states of matter triangle&#x2019; to show the interconversion of states of matter. (c) How can the evaporation of a liquid be made faster?

Philoid · Accepted Answer

(a) We can change the physical state of matter in two ways:

(i) By changing the temperature (heating or cooling).

(ii) By changing the pressure (increasing or decreasing the pressure).

These two factors decide whether a given substance would be in a solid, liquid or gaseous state.

(b)

(c) The rate of evaporation of a liquid can be made faster by

(i) Increasing the temperature

(ii) Increasing the surface area of the liquid

(iii) Lowering humidity and

(iv) increasing wind speed.
