Air is trapped in a piston cylinder arrangement. The air expands from a temperature of 60 C and a pressure of 280 KPa to a pressure of 140 KPa. During the process, 30 KJ/Kg of work is done and 14 KJ/Kg of heat is removed. The initial volume is 0.00878 m^3. a) What is the mass of the air? b) What is the temperature change during this process? c) What is the entropy change during this process? d) Does the...

Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...

Question 2 Gas in a cylinder expands from a volume of 0.85 x 10 cubic meters to a volume of 0.95 x 103 cubic meters, while pressure changes linearly with the volume from an initial pressure of 4.8 atm to a final pressure of 4.0 atm. What is the work done by the gas? You can imagine it does work by pushing a piston that sits on the top of the cylinder (area A) a certain distance Ax and thereby...

Imagine the following design for a simple tire pump The pump is filled with a volume V4 of air at atmospheric pressure pa and ambient temperature Ta When you push the pump handle, the air is compressed to a new (smaller) volume Vf, raising its pressure. A valve is then opened, allowing air to flow from the pump into the tire until the remaining air in the pump reaches the pressure of the air in the tire, pt In this...

answer question clear and complete
3) A weather balloon contains 12.0 mº of hydrogen gas when the balloon is released from a location at which the temperature is 22.0°C and the ambient air pressure is 101 kPa. The balloon rises to a higher altitude where the temperature is -30.0°C and the ambient air pressure is 20.0 kPa. If the balloon is free to expand so that the pressure of the gas inside is equal to the ambient pressure outside, what...
