If you filled a 150ml container with 100ml of substance and the substance quietly filled the container, the substance would most likely be a gas. When a gas is added to a container, it tends to spread out and fill the available space evenly, which is why it can quietly fill the container without causing any disturbance.

To understand the behavior of substances and determine what the substance might be in a given scenario, it is essential to consider their physical properties, such as whether they exist in solid, liquid, or gaseous forms. Additionally, observations like the substance quietly filling the container can help narrow down the possibilities.
