How much work is done by the gas? Two moles of an ideal gas with volume 3 m^3 at 2 atmospYicrcs pressure are expanded isothermally to 6 m^3, then compressed isobarically back to the initial volume then returned at constant volume back to the original conditions. How much work is done by the gas?
An ideal gas is allowed to expand isothermally until it reaches its final volume. It is then heated at constant volume until it reaches its final pressure. The initial state of the gas is P1 = 2.93 atm, V1 = 1.00 L, and Eint 1 = 414 J, and its final state has volume V2 = 2.93 L and Eint 2 = 951 J. 1) Calculate the work done by the gas. Be careful with signs: if the work you...
A sample of an ideal gas is slowly compressed to one-half its original volume with no change in pressure. If the original root-mean-square speed (thermal speed) of the gas molecules was V, the new speed is?

A volume of 100 m3 of a non-ideal gas is contained at 150°C and 50 bar. The gas is then compressed isothermally to a pressure of 300 bar in a well-designed compressor. What is the volume of the compressed gas, how much work is done to compress it, and how much heat must be removed to maintain the temperature at 150°C during compression? You may apply the principle of corresponding states. The critical properties of the non-ideal gas are Tc...

An ideal gas in a cylinder is compressed very slowly to one-third its original volume while its temperature is held constant. The work required to accomplish this task is 77 J. (a) What is the change in the internal energy of the gas? __________J (b) How much energy is transferred to the gas by heat in this process?____________J
105Pa, initial temperature T-300K, and an initial 1. An ideal gas with initial pressure 2 volume V - 1m3 expands isothermally to a final volume of 2m3. Then, the gas returns to its initial state, first by constant pressure (isobaric) contraction, and then by a change at constant volume (isochoric) a) Draw a PV diagram of this process. What's the total change in thermal energy of the entire process? b) What's the work done by the environment on the gas?...
