help please
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 15, Problem 045 Heat engines take input energy in the form of heat, use some of that energy to do work, and exhaust the remainder. Similarly, a person can be viewed as a heat engine that takes an input of internal energy, uses some of it to do work, and gives off the rest as heat.. Suppose a trained athlete can function as a heat engine with an efficiency of 0.12. (a) What is the magnitude of...
