Answer to Question #338601 in Chemistry for pankaj

Question

Helium gas is contained inside a piston cylinder assembly as shown in the figure. Initially the gas is

having pressure 1 bar and volume 0.01 m3. Then the current is supplied, and the gas is heated such that the final pressure is 1.2 bar and the final volume is 0.0145 m3

10 % of the electrical energy supplied to the gas is lost as heat from the cylinder. Determine the followings. If necessary, make assumption(s) with justification.

(a) How long the current is supplied if process is ideal?

(b) How long the current is supplied if process is real?
