Q:

Why does alcohol evaporate faster than water?

A:

Alcohols, such as ethanol and methanol, evaporate at a rate similar to other compounds of their type, but water evaporates comparatively slowly because of its strong bonds. Water molecules easily form hydrogen bonds with one another, which creates a tangled network of attraction within the liquid.

Alcohol can also form hydrogen bonds, but the carbon atoms in its molecules are unable to form such strong connections with each other. This lack of cohesion between carbon atoms allows alcohol molecules to move past each other relatively easily, while water's strong internal attraction creates a resistance to evaporation. This is why water remains liquid from 0 up to 100 degrees Celsius, while most compounds have a much narrower thermal range for their liquid phases.

  • Q:

    Why does water evaporate?

    A:

    Water evaporates because individual water molecules break free of the bonds that hold them all together as a liquid. While water evaporates more in heat, it is possible for it to evaporate in cold conditions.

  • Q:

    What temperature does water evaporate at?

    A:

    There is not a specific temperature that water must be in order for it to evaporate. However, as temperature rises, evaporation typically increases because water molecules are moving more quickly. The faster they move, the more likely it is that they will break away from the pack and evaporate.

  • Q:

    Why does warm water evaporate quicker than cold water?

    A:

    Warm water evaporates faster than cold water as the energy required to release water molecules from the surface is more readily available in the form of heat. Heat is the key to ensuring greater movement between molecules and liberation

    Who discovered ethanol?

    A:

    According to EthanolHistory.com, evidence from pottery believed to have originated 9,000 years ago suggests that Neolithic people in Northern China discovered ethanol and consumed alcoholic beverages. In the first century A.D., the Greeks and the Arabs discovered distillation, a process to increase the ethanol content of alcoholic drinks.
