If the gas expands, the temperature goes down. If the gas is compressed, it becomes hot. Of course the pressure varies also, and the ideal gas conforms to the equation PV/T = constant

Two moles of an ideal gas with C V * = 3R are confined in a piston-cylinder arrangement. The piston is frictionless and the cylinder contains no mechanism for shaft work. Initially, the temperature is 300 K and the pressure is 1 bar Methane (Considered to be an ideal gas) initially at 25. C and 1 bar pressure is heated at constant pressure until the volume has doubled. The variation of the molar heat capacity with absolute temperature is given by ; C P = 20 + 0.001 T. where C P is in J/Kmol . Calculate molar (a) Delta H (b) Delta U 3 0.1 m of an ideal gas at 300 K and 1 bar is compressed adiabatically to 8 bar. It is then cooled at. constant volume and further expanded isothermally so as to reach the condition from where it. started. Calculate : (i) Pressure at the end of constant volume cooling. (ii) Change in internal energy during constant volume process The ideal gas law relates four macroscopic properties of ideal gases (pressure, volume, number of moles, and temperature). If we know the values of three of these properties, we can use the ideal gas law to solve for the fourth. In this video, we'll use the ideal gas law to solve for the number of moles (and ultimately molecules) in a sample of gas This online Van der Waals calculator is based on the Van der Waals equation of state. This was derived by modifying the Ideal Gas equation of state. This theory considers that a gas consists spherical particles which have considerable size and takes into account the molecular interaction forces.It is to be noted that for a given value of P, a, b, n, T there exists 3 uniqu
