Question

Give two reasons to justify-
(a) water at room temperature is a liquid.
(b) an iron almirah is a solid at room temperature.​

Answer 1

(a) At room temperature (25°C), water is a liquid because it has the following characteristics of liquid:

1. At room temperature, water has no shape but has a fixed volume i.e., it occupies the shape of the container in which it is kept.

2. At room temperature, water flows easily.

(b) An iron almirah is a solid at room temperature because its melting point as well as boiling point is above room temperature.

& an iron almirah is also rigid and has a fixed shape. Hence, iron almirah is a solid at room temperature.
