When heat is added to a system, which of the following is not possible?
internal energy of the system increases
work is done by system
neither internal energy increases nor work is done by the system
internal energy increases & also work is done by the system
Q=ΔU+WWhen heat is added to a system, Q is positiveSo if W = 0, ∆ U must be positive∆ U and W both may be positive.
