[2 Marks]

Answer 1

At room temperature $\left({25}^{\circ }C\right)$, water is a liquid because it has the following characteristics:
(i) It has an indefinite shape, which means that it occupies the shape of the container in which it is kept. Moreover it has a definite volume, which means it occupies a fixed amount of space.

(ii) It has a tendency to flows easily, which means it has fluidity.
