Consider a system in which 3.60 mol of an ideal monatomic gas is expanded at a constant pressure of 101 kPa from an initial volume of 2.15 L to a final volume of 3.87 L.
(b) Find the change in temperature for this process.
? K
(c) Determine the amount of heat added to or removed from the system during this process.
? J

physics help please 
drwls,
(b) Since the pressure is constant, T is proportional to V in this process. Use the ideal gas law to get the initial temperature.
(c) Heat added = Internal energy change + work done
= (3/2)R(delta T)*n + P *delta V
