Question 1

If container "A"is occupied by 1.00 mole of oxygen gas while container "B"is occupied by 20.0 grams of nitrogen gas and both containers are maintained at 0.00 ^°C and 650 torr then,

Accepted Answer

The average speed of gas molecules is inversely proportional to the square root of their molar mass. Nitrogen molecules (N2) have a lower molar mass than oxygen molecules (O2), so the average speed of nitrogen molecules in container "B" is greater than that of oxygen molecules in container "A".

Question 2

Which of the following is a condition that must be met for a gas to be considered as "ideal"?

Accepted Answer

For a gas to be considered ideal, the molecules must not exert any forces on each other, meaning there are no interactive forces between them. This is a key assumption of the ideal gas law.

For a substance that remains a gas under all the conditions listed, deviations from the expected values found using the ideal gas law would be the greatest at

Accepted Answer

Deviations from the ideal gas law are greatest at low temperatures and high pressures. At -100°C and 3.0 atm, the conditions are both cold and high pressure, leading to significant deviations.
