An ideal gas expand against a constant external pressure at 2.0 atmosphere from 20 litre to 40 litre and absorb `10kJ` of energy from surrounding . What is the change in internal energy of the system ?

A

4052 J

B

5948 J

C

14052 J

D

9940 J

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaU=q+w`
`=10 xx 1000 -2 xx (20)xx101.3 = 5948 J`

A gas expands against a variable pressure given by P = (20)/(V) (where P in atm and V in L). During expansion from volume of 1 litre to 10 litre, the gas undergoes a change in internal energy of 400 J. How much heat is absorbed by the gas during expansion?

The first law of thermodynamics for a closed system is dU = dq + dw, where dw = dw_(pv)+dw_("non-pv") . The most common type of w_("non-pv") is electrical work. As per IUPAC convention work done on the system is positive.
