A balloon is filled with 5.00 mol of an ideal gas at 50.0 degrees celsius and 1.00 atm pressure. The temperature of the gas is increased to 90.0 degrees celsius while the pressure remains constant at 1.00 atm.
a) Calculate the work (in J) associated with this process.
b) Calculate the heat (J) associated with this process, assuming that the heat capacity of an ideal gas is 20.8 J/mol K.
c) Calculate the change in internal energy (delta E) associated with this process, in J
