To determine whether a liquid is usually lighter or denser than a gas, we need to understand the basic properties of liquids and gases.

Liquids and gases are both states of matter, but they have different characteristics. Liquids have a definite volume, but not a definite shape, meaning they take the shape of their container. Gases, on the other hand, do not have a definite volume or shape and will fill the entire space that is available.

In terms of density, liquids are typically denser than gases. Density is the measure of mass per unit volume. This means that if you were to compare the same volume of a liquid and a gas, the liquid would generally have more mass, and therefore, a higher density than the gas.

So, in answer to the question, a liquid is usually denser than a gas. Therefore, the correct answer is A) denser than.
