You can draw a diagram showing a model of sugar particles dissolving in water particles. As the sugar particles separate, the smaller water particles fit into the spaces between the larger sugar particles. The water and sugar particles are attracted to each other so they move closer together when they are mixed. This is why the total volume is often slightly less than the volumes of the two separate components. by TEDDY

The boiling points of liquids are different so by distillation they can be separated.
A theory models or explains why something is the way it is or how something works. If at some point a scientist find this theory to be inadequate (doesn't fully explain/describe it) due to recent research he/she may have done the theory will need to be modified to include the latest discoveries.
to explain how the project topic works and what it does
He might not of if Malthus had not been around but he depended on the works of Lyell.
you conduct multiple trials so that if a variable was accidently changed in the first experiment you can catch and correct it in the next experiments. this way you get an average answer that can work almost every time. this way you can see if your theory works the same every time. So that we can explain.
A scientific 'theory" is science shorthand for "this is how we think it works". Sometimes the theory is developed without enough information (all the variables are e not known) and later observations and information shows the theory needs to be reworked. With enough information the theory becomes a very good model of what is happening and the changes become fewer and further apart.
The same as the purpose of any physical theory: to explain how our world works.
cause it goes upand down. thats how it works
A gas burner is used in the hot air balloon to heat air. When heat is applied, particles tend to expand. Due to this the air surrounding the balloon is cooler than the air inside it, making it to rise.
Different in volatility.
Distillation works when liquids have different boiling points as you boil then condense the one with the lowest boiling point thus separating them from one and other.
don't know sorry
Distillation can be used to separate solutions of miscible liquids, because the liquids have different boiling points. Distillation works because it vaporizes the more volatile of the two liquids.
Physics regards the physical aspects of the natural world. It includes topics that deal with forces on different bodies within the universe and phenomena that explain how the universe works.

Isopropanol and water form an azeotrope, so you can't use straight distillation. You need to use an azeotropic distillation technique (see the Wikipedia link for details on how this works).
