Chapter 15, Problem 036 GO Under constant-volume conditions, 3000 J of heat is added to 1.3 moles of an ideal gas. As a result, the temperature of the gas increases by 185 K. How much heat would be required to cause the same temperature change under constant-pressure conditions? Do not assume anything about whether the gas is monatomic, diatomic, etc. the tolerance is +/-2% Open Show Work Click if you would like to Show Work for this question:

Chapter 15, Problem 030 GO A monatomic ideal gas (y = 5/3) is contained within a perfectly insulated cylinder that is fitted with a movable piston. The initial pressure of the gas is 2.10 x 105 Pa. The piston is pushed so as to compress the gas, with the result that the Kelvin temperature doubles. What is the final pressure of the gas?

Chapter 22, Problem 56 GO A long, current-carrying solenoid with an air core has 1900 turns per meter of length and a radius of 0.0215 m. A coil of 100 turns is wrapped tightly around the outside of the solenold, so it has virtually the same radius as the solenoid. What is the mutual inductance of this system?
