WebThe first law is put into action by considering the flow of energy across the boundary separating a system from its surroundings. Consider the classic example of a gas … WebHence, the first law of thermodynamics can also be written as shown below when the volume of a fluid changes. ∂ W = - p ∂ V ∂ U = ∂ Q + p ∂ V. The negative sign indicates that the changes in volume are always opposite to the sign of the changes in work. For example, if work is positive, dV would be negative, and vice versa.
