What can you say about

\\\\Delta U,Q

and

W

for the following processess?\ (a) A chemical reaction occurs irreversibly in a well-insulated, rigid bomb. There is an increase in the number of mols such that pressure increases considerably. (Please take the bomb as your system)\ (b) One

kmol

of an ideal gas (

{

(

:C_(pm)=30(kJ)/(k)mol*K),C_(vm)=21.7(kJ)/(k)mol*K

} undergoes a process where its temperature changes from 290 to

340K

. The gas volume is the same at the beginning and the end of the process, although during the process the volume may change. (please take the gas as your system)\ (c) One kmol of the preceding gas expands irreversibly and adiabatically between

P=(10)/(b)ar ,T=400K

and

P=(1)/(b)ar ,T=200K

(please take the gas as your system)
