(ii) At room temperature, water flows easily.


b. An iron almirah is a solid at room temperature (25°C) because: (i) It has a definite shape and volume like a solid at room temperature.

Answer 2

Hey friend

Example 1-. Take a bottle full of coca cola and provide it the temperature about 45°C you will observe it start boiling
then the same cola provide it the temperature of 5-10°C you will find it's start freezing but when you will provide 25-27°C you will see nothing is changed and this temperature we call as room temperature

Same we can try with almirah also vice versa


Hope it helps you ☺
