?

The general gas energy equation is (where $${{\text{Q}}_{1 - 2}}$$ = Heat supplied, dU = Change in internal energy and $${{\text{W}}_{1 - 2}}$$ = Work done in heat units)

A) $${{\text{Q}}_{1 - 2}} = {\text{dU}} + {{\text{W}}_{1 - 2}}$$ B) $${{\text{Q}}_{1 - 2}} = {\text{dU}} - {{\text{W}}_{1 - 2}}$$ C) $${{\text{Q}}_{1 - 2}} = \frac{{{\text{dU}}}}{{{{\text{W}}_{1 - 2}}}}$$ D) $${{\text{Q}}_{1 - 2}} = {\text{dU}} \times {{\text{W}}_{1 - 2}}$$
