"The change in internal energy of a thermodynamical system which has absorbed 2 kcal of heat and done 400 J of work is (1 cal = 4.2 J)"
Added by Shirlin S.
Step 1
- Heat absorbed by the system, \( Q = 2 \, \text{kcal} \). - Work done by the system, \( W = 400 \, \text{J} \). - Conversion factor, \( 1 \, \text{cal} = 4.2 \, \text{J} \). Show more…
