Give two reasons to justify:
$(a)$ Water at room temperature is a liquid.
$(b)$ An iron almirah is a solid at room temperature.

(N/A) Water is a liquid at room temperature because:
$1$. It has a tendency to flow (fluidity).
$2$. It takes the shape of the container in which it is kept,but its volume remains fixed.
$(b)$ An iron almirah is a solid at room temperature because:
$1$. It has a definite shape and a fixed volume.
$2$. It is hard and rigid,meaning it resists change in shape when subjected to external force.
