For a diatomic ideal gas, which plot does NOT correctly describe thermodynamic quantities?

Question

Canvas Classes · Accepted Answer

Strategy:
 Relate thermodynamic quantities (Internal Energy , Enthalpy , etc.) for a diatomic gas to temperature. Recall  and  at moderate temperatures.

Step 1: Evaluate known slopes
-  Plot of  vs  should be linear with slope .
-  Plot of  vs  should be linear with slope .
-  Since , the vertical distance between  and  represents  or .

Step 2: Identify the incorrect plot
Option (3) displays a relationship or slope that contradicts the required ratio for a diatomic ideal gas.
