A group of 50 persons attended a secret meeting in a room 14 m x 10 m x 3.5 m high. The room is completely sealed off and insulated. Each person gives off 150 kCal/hr of heat and occupies a volume of 0.2 m3. The room has an initial pressure 101.3 kPaa and temperature of 16 oC. Calculate the room temperature after 10 min. NOTE: (4.187 kJ = 1 kCal)

One way to cool a gas is to let it expand. When a certain gas under a pressure of 5.00 106 Ha at 25.0C is allowed to expand to 3.00 times its original volume, its final pressure is 1.07 106 Pa. (a) What is the initial temperature of the gas in Kelvin? (b) What is the final temperature of the system? (See Section 10.4.)
A room has dimensions of 7.2 m by 5.9 m by 3.2 m. The pressure inside the room is 90,000 Pa and the temperature is 37 degrees C. Another room with the same dimensions and pressure has a temperature of -7 degrees C. If air has a molar mass of 29 g/mol, calculate the mass of air in each room in kg. Which room has the larger mass of air? Answer in kg rounded to the nearest tenths place.

A 900 g copper rod at 20 degrees celcius has a length of 1.0000 m. The thermal expansion coefficient of copper is 17 x 10^-6 degrees celcius -1. The specific heat capacity is 0.385 kJ/kg degrees celcius. Question A: The copper is heated to 400 degrees celcius. What is the new length? Give the answer in meters and with 4 digits of precision after the decimal. Question B: The hot copper is then quenched by dunking the entire rod in a bucket with 10 kg of water at 20 degrees celcius. The specific heat capaciy of water is 4.18 kJ/kg degrees celcius. If none of the water turns to steam what is the equilibrium temp of the copper rod and water? Please give the answer in degrees celcius Question C: You measure the equilbrium temp and find that it is 24 degrees celcius. If the latent heat of vaporization of water is 2,260 kJ/kg, what mass of water turned to steam? Answer in grams
