  The difference between \[~{{C}_{p}}\] and \[{{C}_{V}}\] can be derived using the empirical relation \[H=U+PV\] Calculate the difference between \[~{{C}_{p}}\]and\[{{C}_{V}}\]  for 10 moles of an ideal gas.                

Answer:

  \[{{C}_{P}}-{{C}_{V}}=nR\] \[=10R\]                 \[=10\times 8.314J=83.14J\]
