Melting Point Of Alcohol

CALCULLA - Table of melting points of substances

calculla.com/melting_point

The melting point is the highest temperature at which crystallization may occur. It is also a temperature at which a solid (crystal) turns into a liquid. We say that such a body melts. The melting point is specific for a given substance. For example, the melting point of ice (frozen water) is 0 °C. The melting point depends on the pressure.

Boiling Points of Ethanol, Methanol, and Isopropyl Alcohol

thoughtco.com/boiling-point-of-alcohol-608491

May 31, 2019 · The boiling point of alcohol depends on which type of alcohol you're using, as well as the atmospheric pressure. The boiling point decreases as atmospheric pressure decreases, so it will be slightly lower unless you are at sea level. Here is a look at the boiling point of different types of alcohol.

Boiling and melting points are physical property of matter. If there is more of a substance; the boiling point will be higher. Freezing points are always 0 o Celsius or 32 o Fahrenheit. All elements have a unique freezing point and boiling point. The mass of a substance affects the boiling point of a substance.
