Why is it difficult to measure the coefficient of expansion of a liquid than solid?

Liquids tend to evaporate at all temperatures.

Liquids conduct more heat.

Liquids expand too much when heated.

Their containers also expand when heated.

Explanation:

All states of matter expand when heated and contract when cooled. Gases expand most when heated and solids the least because gas particles are already far apart and are much freer to move.

As a liquid is heated, its molecules absorb heat and move faster. When the liquid starts to boil, bubbles of vapor form within the liquid and rise to the surface. The temperature that causes this to happen is known as the boiling point of a liquid. When a liquid is heated, molecules move faster.
