Question

An insulated vessel contains 1mole of a liquid, molar volume `100mL` at 1bar. When liquid is steeply passed to `100`bar, volume decreases to `99mL`. Find `DeltaH` and `DeltaU` for the process.
A. 7900 bar ml
B. 8900 bar ml
C. 9900 bar ml
D. 10900 bar ml

Answer 1

Correct Answer - C
Volume of 1 mole liquid `= 100 ml` at pressure one bar `=99 ml` at pressure `100` bar
`W= -P(V_(2)-V_(1))" "DeltaH=DeltaU+P DeltaV`
