Please answer all three parts and show work. Thank you!
1. An ideal gas assumes molecules are point particles and do not interact with each other. In reality, molecules occupy space! To correct for this, the ideal gas equation of state is adjusted to take the volume occupied by the molecules into account for a real gas: PV = nRT or P = nRTV is modified to P = nRT/(V-nb) (IDEAL GAS) (REAL GAS Where "b" is related to the...

Joule Joule -_ Joule Joule cylinder with 20 g of nitrogen gas is mechanically coupled to the environment with a frictionless piston The initial pressure is 1 atm and the initial temperature is 20°C. The gas is then reversibly compressed to half of its initial volume in an isothermal process. Calculate the heat q, work w, change in internal energy ΔU and change in enthalpy ΔH for this process in Joule. You can assume ideal behavior for the nitrogen gas

I can not find the answer to these questions. Everyone is
multiplying liters with pascals and that is not how you get joules.
I tried doing meters cubed times pascals but got the wrong answer.
I thought it was an isochoric process as well so I thought work was
zero but that was also wrong. If anyone knows how to do accurate
thermodynamics, please help me!

Q-1 Air at 1 atm and 20 0C occupies an initial volume of 1000 cm3 in a cylinder. The air is confined by a piston which has a constant restraining force so that the gas pressure always remains constant. Heat is added to the air until its temperature reaches 260 0C. Calculate (a) the heat added (b) the work done by the gas, (c) the change in internal energy of the gas. Q-2 An ideal gas is contained in a...
