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.
(c) Determine the amount of heat added to or removed from the system during this process.
physics help please -
(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
