# Does changing the shape change the volume?

## Does changing the shape change the volume?

Changing the shape does not change its mass or volume, so density remains the same.

### Does plasticine have definite shape?

Wrong concept: Plasticine is not a solid as it has no definite shape. Right concept: A solid can only change its shape if a force acts on it. Plasticine does not change its shape when it is not moulded.

How does the volume of an object change?

Recap the discussion Summarize the idea that volume is the amount of space an object takes up. As long as we don’t add any material or take any away, the volume will stay the same even if we change the shape of the object.

What has a definite volume but its shape changes to match its container?

Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.

## What will be the radius if the volume is doubled?

V = (pi)r2h is the formula for the volume of a cylinder. The formula becomes V = (pi)(2r)2h if the radius is doubled and the height remains the same. V = 4(pi)r2h after simplifying. The volume increases 4 times since the resulting equation is 4 times the original equation.

### Does volume always stay the same?

Even when liquids change their shape, they always take up the same amount of space. Their volume stays the same.

Can you compress plasticine?

Solids have definite shapes and yet, we are able to change the shape of plasticine easily by exerting a force. Conversely, liquids would always take the shape of the container which contains it. On the other hand, plasticine can only be reshaped only when there is a force acting on it. Therefore, plasticine is a solid.

Is plasticine a material?

Plasticine is a putty-like modelling material made from calcium salts, petroleum jelly and aliphatic acids. Plasticine is used for children’s play and as a modelling medium for more formal or permanent structures.

## Do forces change volume?

An force can change the shape and volume of an object.

### Will flow only sideways and down?

Definite means something does not change. The most important liquid to living things is water. This answer is the students’ choice. A _______liquid______ will flow only sideways and down.

Is the volume of plasticine still the same?

Plasticine is a solid and has a definite volume. Hence, the total volume occupied by the plasticine, which is still a solid, remains the same, even when it was reshaped into four smaller balls.

Is the shape of Plasticine a solid or liquid?

Solids have definite shapes and yet, we are able to change the shape of plasticine easily by exerting a force. So, is plasticine a solid or a liquid? Even though plasticine can be reshaped easily, it has a particular shape when left alone and would not take the shape of the container it is in.

## What happens to plasticine if it is left alone?

Even though plasticine can be reshaped easily, it has a particular shape when left alone and would not take the shape of the container it is in. Conversely, liquids would always take the shape of the container which contains it.

### Why do solids have their own shape and volume?

By definition solids have their own shape and volume, whereas liquids have only their own volume. Liquids take the shape of the container in which they are poured, solids do not do this. This happens because of the strength of the intermolecular forces that are present in both solids and liquids.
