At room temperature, sulfur dioxide is a nonflammable, colorless gas that is heavier than air. Its strong, pungent odor and irritating properties usually provide adequate warning of its presence.

The correct answer is option C) It is heavier than air.
Explanation:
When a gas is collected in a gas jar by upward displacement of air, it means that the gas is being collected by filling the gas jar from the bottom with the gas, causing the air to be displaced and rise out of the jar. In this case, sulphur dioxide gas is being collected in the gas jar.
Sulphur dioxide (SO2) is a gas that is denser than air. This means that its density is greater than the density of air. Density is defined as the mass of a substance per unit volume. Since sulphur dioxide gas has a greater mass than an equal volume of air, it is heavier than air.
There are several factors that contribute to the density of a gas, including its molecular weight and the temperature and pressure at which it is measured. In the case of sulphur dioxide, its molecular weight is greater than that of air, which primarily consists of nitrogen and oxygen. Therefore, sulphur dioxide gas has a higher density than air.
It is important to note that the density of a gas can also be affected by temperature and pressure. However, in the context of this question, it can be assumed that the temperature and pressure are constant, so the density of sulphur dioxide gas is solely determined by its molecular weight.
In conclusion, sulphur dioxide gas is collected in a gas jar by upward displacement of air because it is denser than air. Therefore, option C) It is heavier than air is the correct statement regarding the density of the gas.

Sulphur dioxide gas is collected in the lab in a gas jar by upward displacement of the air because Sulphur dioxide gas is heavier than air. The gases lighter than air are collected by downward displacement of water.
