answer the following question

Answer 1

Answer:

From the recorded observation, it can be stated that water is boiled and has been vaporized. Initially, the temperature was 20°C. In each minute, the temperature of water kept on rising by 10°C and finally, it reached to boiling point of water at 8th minute. Now, we saw for the next 4 minutes, the temperature of water remains constant. This is because by the time the temperature reached 100°C, the latent heat of vaporization starts acting i.e. 540 cal or, 2268 J. The temperature remained constant but latent heat is then applied to change the state of water from liquid to gas. After this process gets complete, we'll see the temperature to rise again if it is more boiled.

I hope this helps.
