The work done by 200 calorie of heat in isothermal expansion of ideal gas is:
Open in App
Solution
The correct option is A −836.8 J
From first law of thermodynamics
△U=q+w
Here, △U=0, since process is isothermal.
q=−w
w=−200 cal
So work done will be 200 calorie
Again,
1 cal=4.184 J
So work done = −200×4.184 J=−836.8 J
From first law of thermodynamics
△U=q+w
Here, △U=0, since process is isothermal.
q=−w
w=−200 cal
So work done will be 200 calorie
