suppose that you dissolve 250ml of drink crystals in 1000ml of water. You get 1175ml of drink rather than 1250ml. how can you use the partical model of matter to explain this?

because the crystals dissolve. This is because the water's density is lower, causing it to melt the toaster.

To explain this using the particle model of matter, let's break it down step by step.
First, let's understand the particle model of matter. According to this model, all substances are made up of tiny particles called atoms or molecules that are constantly in motion. When substances dissolve, the particles of the solute (in this case, the drink crystals) separate and become surrounded by the particles of the solvent (in this case, the water).
Now, let's apply this to the given scenario. When you dissolve 250ml of drink crystals in 1000ml of water, the particles of the drink crystals become dispersed within the water. As a result, the particles of the drink crystals take up more space, increasing the overall volume.
So, why do you get 1175ml of drink instead of the expected 1250ml?
One possible reason is that the volume measurements you are using might not be accurate enough. It's important to note that measurements can have slight errors due to instrumental limitations or human error. Therefore, it's possible that the actual volume is closer to 1250ml, but your measurements are slightly off.
Another possible reason is that some of the particles from both the drink crystals and the water may have evaporated during the dissolution process. Evaporation occurs when the particles gain enough energy to escape from the liquid and become a gas. This loss of particles results in a decrease in volume.
Additionally, the dissolved particles may interact with each other, causing them to come closer together. This can result in a decrease in the overall volume of the solution.
In summary, the particle model of matter explains that when drink crystals dissolve in water, the dispersed particles take up more space, increasing the overall volume. However, other factors such as measurement errors, evaporation, and interactions between particles can also contribute to the difference in volume observed.
