An ideal gas is compressed at a constant pressure of 0.80 atm from 19.0 L to 12.0 L. The initial temperature of the gas is 27°C. 1 atm (atmosphere) = 1.013 ~ 10% Pa, 1 L (liter) = 10² m². What is the final temperature of the gas in °C? Hint: pV / T = nR, and n does not change, so you can use piVi / T1 = p2V2 / T2. Do not forget to convert the unit of...
A sample of gas at 760 torr and 2.8 L is compressed at constant temperature to the pressure at 3.5 atm. What is the final volume of the gas? My biggest problem with answering this question is the fact that I don't know what the "constant temperature" is..I know I'm using the combined gas law with formula: V2= p1v1/t1p2 * T2 and that p1=760 torr or 1 atm, v1=2.8L and p2=3.5 atm... Any help on this is very much appreciated.

Calculate the change in entropies (a) ΔS of the system, (b) ΔSgurr of the surroundings, and (c) ΔSuni of the universe when a sample of 0.75 mol of Cl2(g) at 298 K and 1.00 bar doubles its volume in an isothermal reversible expansion. The walls of the container are diathermal (i. e. , they are thermally conducting). Assume that under these conditions Cl2(g) behaves as an ideal gas.
