Q:

Why does alcohol evaporate faster than water?

A:

Quick Answer

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.

Full Answer

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.

    What is antifreeze made of?

    A:

    Most antifreeze is made from ethylene glycol, but it can contain other chemicals or ingredients, such as propylene glycol, ethanol, methanol and isopropyl alcohol. Some modern types of antifreeze include chemicals that allow them to last twice as long as conventional fluids, while other antifreeze types use propylene glycol as the main ingredient, resulting in a product that is much safer for pets and humans.

  • 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
