Pedro is an Electrical Engineer working for Boeing, and is working on the ion propulsion system for Arman's New Horizon 2 mission to Charon, Pluto's largest moon. The ion propulsion system stores 2 m3 of Krypton gas in a rigid tank at a pressure of 3 atmospheres (1 atm = 101,000 kPa). On Earth this gas is at room temperature, 68°F (20 °C). How much heat will the gas lose by the time it reaches the far side of the moon, where the temperature is -171 °C, just before the ion propulsion system is activate?

Pls.answer thank you! A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5 KW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 KJ/hr. There are 10 light bulbs in the room, each with a rating of 100 watts. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 KJ/hr. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.
