A flexible balloon contains 0.320 mol of hydrogen sulfide gas ({\rmH}_{2}{\rm S}). Initially the balloon of {\rm H}_{2}{\rm S} has avolume of 6600 cm^3 and a temperature of 21.0^\circ C. The {\rmH}_{2}{\rm S} first expands isobarically until the volume doubles.Then it expands adiabatically until the temperature returns to itsinitial value. Assume that the {\rm H}_{2}{\rm S} may be treated asan ideal gas with C_p = 34.60\;{\rm J/mol \cdot K} and \gamma =4/3.
a) What is the total heat Q supplied to the {\rm H}_{2} {\rm S} gasin the process?
b) What is the total change in the internal energy DeltaU of the{\rm H}_{2}{\rm S} gas?
c) What is the total work W done by the {\rm H}_{2} {\rm S}gas?
d) What is the final volume V?
Can someone help please?
