One kilogram of steam is placed in a piston-cylinder device, initially at P 5 1 bar and T 5 1008C. The steam is heated at constant pressure to T 5 2008C. A. Find the heat and work for this process....

One kilogram of steam is placed in a piston-cylinder
device, initially at P 5 1 bar and T 5 1008C. The
steam is heated at constant pressure to T 5 2008C.
A. Find the heat and work for this process. Obtain all
needed data from the steam tables.
B. Find the heat and work for this process. Use the
ideal gas law and the ideal gas heat capacity for
steam, located in Appendix D. How far off are
your answers compared to part A?
C. Suppose in part A you had overlooked the fact
that the steam expands when heated, and assumed
that work was negligible. How far off would your
answers for Q have been?
