Question

21. In which of the following conditions, increase
in internal energy (AE > 0) is maximum ?
1) q = 500J;W=-200J 2) q=-400J; W=+200
3) q=500J; W=200J 4) q=400J ; W=100J​

Answer 1

Answer:

3rd will be correct answer

When work done is positive so internal energy is maximum

Explanation:

U=q+w
