An ideal gas is held at a constant temperature of 390 K as it expands slowly from a volume of 0.50 m² to 5.2 m³. As the gas expands, it does 240 J of work. What is the change in the internal energy AU of the gas during this process? AU = 240 Incorrect How much heat Q is absorbed by the gas as it expands?

A heat engine using 1.0 mol of a monatomic gas follows the cycle shown in the figure. 3750 J of heat = 37507 A heat engine using 1.0 energy is transferred to the gas during process 1 - > 2. (Figure 1) AE₁-2 mol of a monatomic gas follows the cycle shown in the figure. 3750J of heat energy is transferred to the gas S → 3 in this cycle.
