Answer in units of J. 010 (part 2 of 2) 10.0 points How much energy must be added to the gas by heat for the indirect path IAF to give the 2 same change in internal energy? Answer in units of J.

Answer 1

The change in internal energy of the gas is 117 J.

Step-by-step explanation:

The change in internal energy of a gas can be calculated using the first law of thermodynamics. The first law of thermodynamics states that the change in internal energy (ΔU) of a system is equal to the heat added to the system (ΔQ) minus the work done by the system (ΔW):

ΔU = ΔQ - ΔW

In this case, the heat added to the gas is 117 J and there is no work done by the gas, so the change in internal energy is:ΔU = 117 J - 0 J = 117 J

The change in internal energy is 117 J.
