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?

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.
Note. Write your answer step by step and clearly explain your work. You need to upload a

See below for details: -Your work is replacing a chiller that is used as part of a distillation process that condenses methanol (boiling point = 65 °C). Your task is to select the most economical type of system. A conventional chiller will have a lower first cost and will have lower maintenance costs than one that involves enhanced heat transfer surfaces, but the chiller with enhanced surfaces will condense the same amount of alcohol with a lower energy consumption. Select the appropriate chiller by considering the net present value of both systems. That value will involve the first cost of the chiller, and the present value of the maintenance and energy costs. The chiller uses a standard vapor-compression refrigeration cycle with R-22 (see Figure 1).

- *** 32. A double-chambered container contains one mole of helium in one of its 1000 cm³ Pull to volume chambers. The container is well-insulated, and of low specific heat, so that no appre- remove ciable heat is added to the gas during the process we describe. The gas is initially at a tempera- ture of 300 K and a pressure of 1 atmosphere. The partition between the two chambers is then quickly raised, and the gas expands freely to fill the entire container. Whenever a monatomic gas like helium doubles its volume adiabatically like this, the pressure in the gas will drop to 0.315 of what it was before (for reasons that we did not explain in this chapter), so the final 1000 cm3 1000 cm³ pressure of the expanded gas will be 0.315 atmospheres. a) What is the temperature of the gas after the expansion? b) What is the change in the internal energy of the gas? c) How much heat is added to the gas?
