Water is to be boiled at atmospheric pressure in a polished copper pan placed on top of a
heating unit. The diameter of the bottom of the pan is 00.2 m. If during 30 minutes the water
level is dropped by 0.1 m, calculate the inner surface of the bottom of the pan.
Assumptions 1 Steady operating conditions exist. 2 Heat losses from the heater and the pan
are negligible 3 The boiling regime is nucleate boiling.

AH of vaporization of water is 439.2 cal/g at the normal boing point. Since virus can survive at 404.39 K by forming
spores. Most virus spores die at 851.9 K. Hence, autoclaves used to sterilize medical and laboratory instruments are
pressurized to raise the boiling point of water to 851.9 K. Find out at what InP (torr) does water boil at 851.9 K?
