The standard enthalpies of formation, at 25.00 oC, of methanol (CH4O(l)), water (H2O(l)), and carbon dioxide (CO2(g)) are, respectively, -238.7 kJ/mol, -285.8 kJ/mol, and -393.5 kJ/mol. Calculate the change in the entropy of the surroundings (in J/K) upon the combustion of 16.9 g of methanol under a constant pressure of 1.000 atm and a temperature of 25.00 oC. N.B. combustion is the reaction of this substance with molecular oxygen to produce water and carbon dioxide.
A 1.75 L volume of helium gas stored at 0.873 atm will have a temperature of 46.9oC. If the helium is compressed down to a volume of 523 mL while allowing the pressure to settle at 1,662 mmHg, what will the temperature of the helium gas now be, in oC? Give your answer to one decimal place, and in units of oC. Data: 1 atm = 760 mmHg, 0oC = 273 K, PV = nRT, R = 0.0821 L.atm.mol-1.K-1.
One mole of Ar gas is compressed by an external pressure of 2.00 atm, to a final volume of 10.0 L from an initial volume of 20.0 L. Using calorimetry, 1.00 kJ of heat is observed to flow from the gas. What is the work for this process? Please show all steps.

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...
