A container initially at 323 K is heated to a final temperature of 573 K. If the device contains a mixture of nitrogen and oxygen along with other minor products is approximated as "lab air," and frictional effects are neglected.
(a) if the system is in a rigid container, how much heat and work are required assuming the container is V = 0.05 m^3 and the initial pressure is 450 kPa for the most efficient manner of heating? Assume constant Cv, Cp and R
(b) suppose the cntainer has one wall which is able to expand (no movement restriction) what is the increase in the heat needed to accomplish the process? Use Po & Vo from part a.
(c) if the sliding container from b is placed in an environment at 450 kPa & 298 K what is the final volume, temperature & pressure of the containers contents?
