Could gas and liquids flow into a container?
Although they are both fluids, it depends on the type of container.Liquids can usually be carried in open- or closed- containers. Mugs and glasses (tumblers) are examples of open containers. A soda bottle with a screwcap or any kind of container that seals the contents against the atmosphere are examples of closed containers.Liquids carried in closed containers may need protecting from the atmosphere (brake fluid is hygroscopic and the container must always be sealed when stored) or it may be that the liquid gives off fumes (like ammonia) which may harm the carrier or the environment.Unless they are particularly heavy, gases are generally only carried in closed or sealed containers as they may cause harm to the environment.
