Meritnation experts pls answer the following questions

4.by applying high pressure and reducing temperature we can liquify gases

(B) liquid

2.a._ water will stay in gaseous state at 250 degre Celsius. 2.b._ water will stay in both liquid and gaseous stay because at that temperature the water only starts boiling. 3. Because the heat energy which is supplied is used up in over coming the force of attraction between the particles and hence changes the state. 4. By increasing pressure and lowering temperature.

Dear megha if really like my answer then please go to YouTube and search Gopal Nutan Shaw . It is my brother's channel please subscribe

Sorry

But who are you to say me khadus

Dear student ,

Temperature of any substance remains constant because the heat supplied to increase the temperature is utilised in changing the state of matter.
Since the heat is used to overcome the force of attraction, the temperature of the substance does not change. The heat energy absorbed in this case is called as the latent heat.

2a.water vapour or gas
2b.liquid or gas both can be their due to latent heat of fusion

3. Due to latent heat of fusion

Increasing the temperature and decreasing the pressure
