Question

calculate the work done if Temperature is change from 0°to 200° at 1 atm is
100cal
200cal
400cal
800cal​

Answer 1

Answer:

you are a brilliant student you can do it by yourself

Answer 2

Answer:

Solution:- (D) 120J

As the work is done by the system and heat is supplied to the system.

Therefore,

q=100 cal=420J

w=−300J

Now from first law of thermodynamics,

ΔU=q+W

∴ΔU=420+(−300)

⇒ΔU=120J

Hence the change in internal energy during the process is 120
