Of heat is extracted from the system, ∴ dQ = − 70cal. = − 70 × 4.2J ∴ d Q = - 70 c a l. = - 70 × 4.2 J Noe, dU = dQ − dW d U = d Q - d W = − 70 × 4.2 − ( − 300)J = - 70 × 4.2 - ( - 300) J dU = − 294 + 300 = 6J d U = - 294 + 300 = 6 J. WebIn thermodynamics, work performed by a system is the energy transferred by the system to its surroundings. Work is a form of energy, but it is energy in transit. A system contains no work, and work is a process done by or on a system. In general, work is defined for mechanical systems as the action of a force on an object through a distance.
