What is it called when you burn something with a magnifying glass?

A magnifying glass uses a lens. Lenses are curved objects that have a different density to air, thereby warping what we see through them. It is important to understand that when light enters a material of a different density, it changes velocity. Magnifying glasses are convex, which bends the light in such a way that it seems to magnify objects when seen from a certain distance. At a certain distance from the glass, all the light rays are concentrated at one point. If a bright object, such as the sun is present, this point can get very hot. By placing an object at this point, all the energy from the light is directed at this one point, causing intense heat which will lead to burning.

Why do people use alcohol in thermometers instead of water?

Firstly, mercury has a freezing point of about -38Co. So a mercury thermometer cannot be used below this. Alcohols have a much lower freezing point, some around -100Co .

Alcohols however have lower boiling points, and this limits the maximum temperature at which they may be used.
