28 J of work is done by the system
The first law of thermodynamics states that energy can be converted from one form to another with the interaction of heat , work and internal energy , but it cannot be created nor be destroyed .
first law of thermodynamics can be mathematically written as , it can be represented as :
del U = q + w
del U = total change in internal energy of a system
q = heat exchange between system and its surrounding
w = work done by or on the system
final internal energy - initial internal energy = q + w
93 - 58 = 63 + w
work done = - 28 J
28 J of work is done by the system
correct option a) 28J
