Situation 1: A gas expands at constant pressure P1 from volume V1 to volume V2. It is then kept at constant volume while the pressure is reduced to P2. Situation 2: A gas is reduced in pressure from P1 to P2 while its volume is held constant at V1. It is then expanded at constant pressure P2 to a final volume V2. In which of the processes is more work done by the gas? Why?

step 1: Read the problem carefully. Step 2: Draw a diagram. Step 3: Gather data. V1 = 2 m3 p1 = 105 N/m2 t1 = 27°C pressure is doubled p2 = 2p1 = 2 x 105 N/m2 volume is constant V2 = V1 = 2 m3 calculate T2 = ? or t2 = ? Step 4: Determine which formula to use, substitute numerical values, and calculate the required values. Although if V = constant we could use Gay-Lussac's Law, we...

1) A weather balloon filled with He gas to a volume of 262 L on a day when the temperature was 18°C. The balloon was only released the next day when the temperature was -10°C. Calculate the new volume of the weather balloon. Assume that the atmospheric pressure remained the same on both days. 2) The volume of an empty flask with a one-holed stopper was 285 ml (V1). You heated the flask for 1 minute (T1) and then cooled...

8. Initially, 1 mole of the real gas is contained in a thermally insulated piston-cylinder arrangement in an initial state (T1, P1, Vi ). 1 mole of the real gas that is expressed by the following equation of state under the investigation. Now, the gas is expanded so as to fill the final state of (T2, P2, V2 ). Suppose that any possible temperature dependence of Cy is negligibly small and the molar heat capacity is approximately equal to 2"...

2 moles of compressed air (diatomic gas) in a cylinder under the initial condition T1=573K p1=500kPa. Found v1=0.019m^3 but can not remember then how to find V2. I think that it has something to do with T1=T2 condition then P2 can be found.... but stuck on how to proceed so with FULL written explanations with working would be much appreciated! All question info on practice exam below - note ISOTHERMAL EXPANSION. for part ii which after an explanation first. Two...
