Question

Give two reason to justify-
{a} water at room temperature is a liquid.
{b}an iron almirah is a solid at room temperature​

Answer 1

Answer:

here's your answer...

(a)At room temperature (25°C), water is a liquid because it has the following characteristics of liquid: 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. 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. Similarly, (i) An iron almirah is rigid and has a fixed shape. (ii) The density of metal is quite high. Hence, iron almirah is a solid at room temperature.

Answer 2

Answer:

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:

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.

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:

It has a definite and rigid shape and

Fixed volume like a solid at room temperature.

On applying external force the shape does not get deformed
