Question

1. Why are the number of atoms in one mole of carbon less than the number of atoms in one mole of O2 gas?

I would think that the number of atoms in one mole of carbon would be equal to the number of atoms in one mole of oxygen gas but apparently not. Can someone please explain?

2. Suppose the absolute temperature of an ideal gas is doubled from 100 K to 200 K. Does the average speed of the molecules in this gas increase by a factor that is greater than, less than, or equal to 2?

The answer is less than 2 but can someone explain why?

Explanation / Answer

1. Oxygen gas has two atoms per molecule. It is O2. Thus, number of atoms will be double in case of O2 than in carbon (C).

2. Average speed is proportional to sqrt(T).
Thus, if temperature doubles, average speed will increase by factor of 1.41
