Chapter 6, Problem 6.34P

QUI A piston-cylinder device with a set of stops initially contains 300 g of steam at 1000 Kpa and 400 C. Find the work if the final state IMpa and 250 C, and work if the position of the stops corresponds to 60% of the initial volume and also find the temperature at the final state if P-500Kpa Steam 300 g 1000 Kpy 400°C e

If 528 kJ of heat are added to 2.25 kg of helium at constant volume process when the initial temperature is 40 deg. C, find: the change in enthalpy in kJ 869.5 889.5 879.5

A piston/cylinder has a water volume separated in VA = 0.3 m³ and VB = 0.4 m by a stiff membrane. The initial state in A is 1000 kPa, x = 0.8 and in B it is 1500 kPa and 250°C. Now the membrane ruptures and the water comes to a uniform state at 200°C. What is the final pressure? Find the work and the heat transfer in the process. Po mp cb A:H2O B:H20

Two kilograms of Methane gas underwent an isopiestic process from 200C to 300C. Find the change in internal energy, change in enthalpy, work done and heat transferred. Sketch the T-s and P-v diagrams.

I want... third one..make it fast

Please solve briefly

find the volume of 2.3 kg of dry staurated steam at 11000 kpa  ?.

3kg of Co2 expanded in a stationary piston cylinder through a polytropic process from 30 degree Celsius and 250 kpa to 100kPa pressure. If the polytropic exponent, n = 1.45, find the total work, total heat transferred, total kinetic energy change and internal energy change
