CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Gases don’t have a fixed shape or a fixed volume. The particles move around all the time and spread out. This is why a gas fills its container. A gas can be compressed into a very small space – this pushes the particles closer together.

Detailed explanation-2: -Gases: As a gas, molecular compounds have neither a defined volume nor shape. Like liquids they flow to adopt the shape of the container, but unlike liquids, they also expand to fill the volume of the container that holds them.

Detailed explanation-3: -Dalton’s Law of Partial Pressures An ideal gas will expand in a container to fill up the space it is in and does not have any forces of attraction between the molecules. In other words, the different molecules in a mixture of gases are so far apart that they act independently; they do not react with each other.

Detailed explanation-4: -A gas is matter that has neither a fixed volume nor a fixed shape. Instead, a gas takes both the volume and the shape of its container. It spreads out to take up all available space.

Detailed explanation-5: -Because gases expand to fill their containers, it is safe to assume that the volume of a gas is equal to the volume of its container. The difference between the volume of a gas and the volume of the liquid or solid from which it forms can be illustrated with the following examples.
