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:

(c) `Q=mcDeltaT`
`rArrQ=mc(T-t_0)…..(i)`
`:.` From 50K to boiling temperature, T increases
linearly.
During boiling, equation is
`Q=mL`
Temperature remains constant till boiling is complete
After that, again eqn. (i) is followed and temperature
increases linearly.
