Question

An system has internal energy to e1,450j of heat is taken out it and 600j of work is done on

Answer 1

Dear Student

Heat given out by system = -ve = - 450 JWork done on system = +ve = + 600 JThus, by first law of thermodynamics, ∆ Internal energy = E2 - E1= heat + work = -450 + 600 = 150 JTherefore, there is increase of internal energy by
