The atoms in the gas contract or retract from each other in order to fill a container. Therefore, the pressure increases/decreases as the atoms come closer/farther from each other and the edges of the container.

What is a substance that does not have shape or volume but can expand and take up space?

A gas is a substance that does not have a fixed shape or volume. It can expand to fill the space available to it.


What does not have a definite shape and does not take up a definite amount of space?

Matter that has no definite shape or volume is a gas.


Which state fills up the container it is placed in?

A gas fills up the container it is placed in because gases do not have a fixed shape or volume. They expand to fill the available space of the container.


How does a gas take up the shape of a container?

It will completely fill the container.


Has no shape of its own but fills up a certain amount of space?

A gas is a substance that has no definite shape and takes the shape of its container, but it still occupies a certain amount of space. Gas particles are free to move past each other and spread out to fill the space available to them.


Does gases take up a definite amount of space?

Gases do not have a definite shape or volume because they expand to fill the container they are in. This is due to the fact that gas particles are in constant, random motion and spread out to fill the available space.


What is a kind of matter with a volume and a shape that both change to fill up empty space?

This is the definition of a gas.


What determines the shape a volume of a gas inside a container?

The shape of the gas is determined by the shape of the container (assuming that there is enough gas to fill the container). The volume of the gas is determined by the volume of the container (again assuming that there is enough gas present to fill the container.). When a gas is introduced into any container, it will assume the size and shape of the container if the container is filled. The exception to this rule might be if the pressure of the gas introduced is great enough to influence the shape of the container (i.e. blowing up a balloon).


Does gas have volume and shape?

The volume of a sample of liquid is fixed, but may expand or contract with heat. The shape of a liquid is defined by its container. In the absence of gravity, liquids outside a container will assume a generally spherical shape.


How can gas fill a container of any size or shape?

it goes by the kind of car you use a t what brand gas was always used in it when u bought it. if you are buying a brand new car then u start it off of what kind of gas will be used and being that gas is a liquid it just flows in any kind of car hole because all cars have whole openings for gas. Personally I don't think the above person understood the question... A gas is able to fill a container because it has no fixed volume or shape, therefore using diffusion to fill the empty spaces; now you have a container full of a gas.


What determines the shape and volume of a a gas inside a container?

The shape of the containerA property of a gas is that it expands to fill the shape and volume of a container. An exception may be the case where there is more than one gas and the heavier gasses will tend to settle to the bottom of the container.


Does a gas have an indefinite shape?

Yes, a gas does not have a definite shape and will expand to fill the container it is placed in. This is because gas particles move freely and in random directions, spreading out to take the shape of their container.
