You can use density to describe the arrangement of particles in different states of matter i.e. solid, liquid and gas.
Do you know what the 3 states of matter are? Select 3 options from the list below.
You can select multiple answers
Which of the following do you think best describes the arrangement of particles in a solid?
Which of the following do you think best describes the arrangement of particles in a liquid?
Have a good look at this image.
It shows the structure of a solid, a liquid and a gas.
Given the image shown on the previous slide, which of the 3 states of matter do you think is the most dense.
Why is a solid more dense than a liquid or gas? Pick all the options that you think are correct.
You can select multiple answers
To sum up, because the particles in a solid are closer together than in a liquid and a gas a solid is the most dense of the 3. This is because there is less of a gap between the particles, so there is more of a material in a set volume.
True or false? The particles in a solid are always arranged the same, no matter what the solid is?
True or false? A solid is always denser than a liquid.
To sum up, an object will float if the **** density of the **** object is less than the density of the liquid it is placed in. This does not mean that the object is **** lighter than the liquid. It just means that it is less dense. Some solids are not very dense.
