Suppose that there is 2.43 mol of nitrogen gas in an insulated, sealed 31.7-L container initially at 285k. The specific heat of nitrogen gas is 1.04 kJ kg^-1 K^-1 (note units). If a 5.44-kg block of iron at 755 K is placed in this container and it is sealed again (with no loss of nitrogen), what is the final pressure of the nitrogen gas?
