In the hypothetical movie Despicable Me 11, Gru and Dr. Nefario invent a hard plastic bubble to encapsulate the minions so they can sneak up on the villian's base on the surface of the moon. The bubble basically serves as a hamster ball for the minions. Kevin volunteers for the first trial of the bubble. Inside Gru's base at 22 degrees C, they fill the bubble with 1 atm of air. Kevin rolls the bubble through the airlock onto the surface of the moon in daylight, where the temperature is 120 degrees C. What is the new pressure inside the bubble in atm?

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.
