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

a) Water at room temperature is a liquid.

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.

An iron almirah is a solid at room temperature (25°C) because:

1. It has a definite and rigid shape and
2. Fixed volume like a solid at room temperature.
3. On applying external force the shape does not get deformed
