An equal mass of which of the following states of matter could completely fill either a 100 mL or 500 ml container? A. Mixture
B. Liquid
C. Solid
D. Gas

Matter is defined as a substance that has mass and occupies space. The matter can be classified into solids, liquids, and gases based on their properties.

The correct answer is:

Option D. Gas

The properties of the gas are:

1. Gas is defined as the state of matter, which occupies the whole space of the container and does not have a fixed shape.

2. The gas particles are in random motion and have no fixed volume or shape. The density of the gases is lower than solids and liquids, the spaces between the gas particles are maximum.

3. The container of 100mL or 500 ml will be filled by the state of matter, gas.

Thus, the correct answer is Option D.

Gas

Explanation:

An equal mass of gas could completely fill either a 100 mL or 500 ml container. It should be noted that in their composition, gases are very versatile and can therefore either expand or contract its molecular make up.so as to be able to fill containers of different size.

Therefore, gases are able to fill containers whether the container is large or small with equal mass just by altering its molecular organization.
