Liquid oxygen at 50 K is heated to 300 K...

Liquid oxygen at `50 K` is heated to `300 K` at constant pressure of `1 atm`. The rate of heating is constant. Which of the following graphs represents the variation of temperature with time?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Temperature of liquid oxygen will first increase in the same phase. Then, phase change (liquid to gas) will take place. During which temperature will remain constant. After that temperature of oxygen in gaseous state will further increase.
