Calculate the heat capacity of a gas sample from the following information: The sam- ple comes to equilibrium in a flask at 25°C and 121.3 kPa. A stopcock is opened briefly, allowing the pressure to drop to 101.3 kPa. With the stopcock closed, the flask warms, returning to 25°C, and the pressure is measured as 104.0 kPa. Determine Cp in J mol- K-l assuming the gas to be ideal and the expansion of the gas remaining in the flask to be reversible and adiabatic.

A tank contains 192 kg of water at 113 kPa. 108 kg of water is in the liquid form and the rest is in the vapor form. The saturation temperature is 100.5 C, the specific volume of saturated liquid is 0.001040 m³/kg, and the specific volume of saturated vapor is 2.7808 m³/kg. a. Draw the P-v diagram to represent the phase transition from water, and specify the phase regions and lines explicitly. b. Mark the numerical values on the diagram, and determine the total volume of the mixture?
Carbon Dioxide (M=44) is being stored at 46°C, 80 bar. The critical temperature and pressure are 31°C and 72.8 bar. Calculate the specific volume. (0.004 m³/kg)
A 0.1 kg block of pure copper at a temperature of 250°C is dropped into a 4°C water bath. The bath contains 0.03 m^3 of water and is well insulated. Find the final temperature after the block and the water reach thermal equilibrium. (It is reasonable to assume the following: the specific heat of water is equal to the value at 4°C; the specific heat of the material in the block can be taken to be a constant value evaluated at a temperature mid-way between the initial temperatures of the block and the water.)
I am stuck on this question, please explain. Thank you!
An ideal gas of 4kg mass (MW=3g/mol and k=2.3) contained in a regulated mass system went through three processes in a cycle, one after the other. The initial conditions for the gas were 20kPa and 310K in the first step, and the pressure was isometrically increased by 30kPa. The gas was heated to 400 degrees Celsius using a technique defined by the equation PV3=C. Upon returning to its previous state, it exhibits polytropic behavior. Calculate the change in entropy for each of the processes.
Can someone please answer part a and part b. but please transform the PV diagram to a TS diagram first and express Ti in terms of Cp, Cv, TL, and TH
