Question

When a gas is compressed ,the work obtained is 360 J while the heat transferred is 190 J .Hence the change in internal energy is

Answer 1

Answer:

(A) increases by 360J

As given that work is done by the system and heat is absorbed by the system.

Therefore,

q=36kJ

w=−10kJ

Now from first law of thermodynamics,

ΔU=q+w

⇒ΔU=10+(−6)=3J

⇒Uf −Ui =3⇒Uf =(Ui+3)

Hence the internal energy is increased by 3kJ

Answer 2

Answer:

-170

Explanation:

-360+190=-170

so hence work is -170j
