At any temperature a liquid partly vaporizes into the space above it until the pressure exerted by the vapour reaches a characteristic value called the vapour pressure of the liquid at that temperature. Alternative water extraction technologies are developed for dry areas where no water sources are available. In small amounts acetone burns with a dull blue flame, in larger amounts the evaporation of fuel causes incomplete combustion and a bright yellow flame. Combining both the equations we can write. Note that these formulas use specific units: This product can further combine with another acetone molecule, with loss of another molecule of water, yielding phorone and other compounds. Explanation: Acetone 56.0 C. At sea level, water boils at 100 C (212 F). The following graph will make it clear that how intermolecular forces effects the temperature. As a good solvent for many polar and non-polar organic compounds, it is used to clean contaminated surfaces, as a solvent for paints, varnishes, various organic synthetic reactions, etc. Actually the boiling point of acetone Me2C=O is surprising high compared to isobutylene Me2C=CH2. Latest posts by Dr. Mariam Bozhilova Forest Research Institute, BAS, Acetone is the simplest ketone, also known as dimethyl ketone or propanone. [45], Small amounts of acetone are produced in the body by the decarboxylation of ketone bodies. Which statement about distilling a mixture of acetone and water is correct? The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to .
