Gases can change volume because they take up the whole space of the container, room, etc. that they are contained in.

Gases can change volume because their particles are not held together tightly like in solids or liquids. The particles in a gas are free to move around and spread out to fill the available space, so when the pressure or temperature changes, the volume of the gas can adjust accordingly.
Yes, gases have volume. However, gases are compressible and take the shape of their container, so their volume can change based on pressure and temperature.
Gases do not always keep the same volume. Gases can expand to fill the entire volume of a container or be compressed into a smaller volume depending on changes in pressure and temperature.
Increasing pressure can compress the particles of a substance closer together, increasing the density of both solids and liquids. In gases, increasing pressure causes the gas particles to come closer together, decreasing the volume and increasing the density.
Gases do not have a definite volume. They will expand to fill the container they are in, taking on the shape of that container.
Yes, the volume of air can change based on factors such as temperature, pressure, and the presence of other gases. When air is heated, it expands and its volume increases. Conversely, when air is cooled, it contracts and its volume decreases.
