The gas is cooled such that it loses 65 J of heat . The gas contracts as it cools and work done on the
system equal to 20 J is excharged with the surrounding . What are q, w and `DeltaU`?

Text Solution

Verified by Experts

The correct Answer is:
`q =- 65 J ; w = 20 J ; DeltaE = - 45 J`
` q = - 65 J, W = + 20 J`
`DeltaE = - 65 + 20 = - 45 J`
