Question

2.(06.01 MC)

The graph compares the kinetic energies of the molecules in four gas samples. Each graph shows a normal distribution, so the average is the center.
Fraction of Molecules
Kinetic Energy
Which sample is likely to have the lowest temperature? (1 point)

Answer 1

The gas A is likely to have the lowest temperature

Step-by-step explanation:

In a gas, the kinetic energy is directly proportional to the temperature under constant pressure and volume.

As you can see in the problem, the average of A has a low kinetic energy. But the average is increasing between B, C and D.

As the gas A has the lowest average kinetic energy:

The gas A is likely to have the lowest temperature
