Suppose 1.15 mol of oxygen is heated at constant pressure of 0.75 atm from 13.0° C to 22.0° C.
(a) How much heat is absorbed by the gas?
J
(b) Using the ideal gas law, calculate the change of volume of the gas in this process.
L
(c) What is the work done by the gas during this expansion?
(d) From the first law, calculate the change of internal energy of the gas in this process.
