A piston-cylinder contains 5 kg of an ideal gas (cv = 0.7 kJ/kg∙K, R = 0.3 kJ/kg∙K) at 100 kPa and 327ºC. The gas is cooled at constant pressure until it loses 1000 kJ of heat. Determine the entropy change of the gas, in kJ/K, and the required temperature of the surroundings in order to assure that there is not a violation of the second law of thermodynamics?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

In a heat engine if 1000 j of heat enters the system and the piston does 500j of work, what is the final internal energy of the system if the inital energy was 2000 j1.write the equation2.list out your known variables 3. plug the numbers into the equations4.solve 5.write your solution statement that includes initial energy and final energy added.

Acar of mass 800kg is moving at a speed of 2.2m/s.
