If liquefied oxygen at 1 atmospheric pressure is heated from 50K to 300k by supplying heat at constant rate. The graph of temperature vs time will be

Text Solution

Verified by Experts

The correct Answer is:

In teh first phase temperature of liquid oxygen will increase. In the second phase, when liuqid oxygen changes to gas, temperature will remain constant. In the third phase, the temperature of oxygen is gaseous state will further increase.
