Insulating windows. One way to improve insulation in windows is to fill a sealed space between two glass panes with a gas that has a lower thermal
81. Give one reason why the noble gases are preferable to air (which is mostly nitrogen and oxygen) as an insulating material.
- A. Noble gases are monatomic, so no rotational modes contribute to their molar heat capacity.
- B. Noble gases are monatomic, so they have lower molecular masses than do nitrogen and oxygen.
- C. The molecular radii in noble gases are much larger than those of gases that consist of diatomic molecules.
- D. Because noble gases are monatomic, they have many more degrees of freedom than do diatomic molecules, and their molar heat capacity is reduced by the number of degrees of freedom.
