When placed in a 200-mL square box, a substance has a spherical shape and has a volume of 75

mL When placed in a 200-mL circular tube, the same amount of that same substance has a

spherical shape and a 75-mL volume. In which of the following states is the substance?

solid

liquid

gas

Solid

Explanation:

A solid maintains a constant shape and a constant volume.

B is wrong, because a liquid maintains its volume but assumes the shape of the container.

C is wrong, because a gas maintains neither a constant shape nor a constant volume.

solid

Explanation:

First let's look at the difference between the states of matter

Most solids maintain their shape regardless of where they are contained

Liquids and gases take the form of the container that contains them

In addition the gases expand their volume and tend to occupy the entire surface where they are contained

For example, if we have a certain volume of water in a square container, the water will have this shape

If we take the same volume and place it in a spherical container it will stop being square and will adapt to the spherical shape

At the beginning it is placed in a square box and they tell us that it maintains its spherical shape then it is contained in a spherical container and maintains its shape and volume

It maintains its shape and volume regardless of the container that contains it, therefore it is in a solid state
