Boiling point

Boiling Point, Philip Barantini’s hit British indie one-shot film starring Stephen Graham, is to be made into a BBC TV series charting events six months after the movie took place. Graham and…

If you add salt to water, you increase its boiling point (the temperature at which it boils). Do you know why this happens?

The two most commonly used temperature scales are Celsius and Fahrenheit. The Celsius scale, named after Swedish astronomer Anders Celsius, sets 0C at the freezing point of water and 100C as the boiling point of water at 1 atmosphere of pressure — normal air pressure at sea level. The Fahrenheit scale has 32F as the freezing point of water and 212F as the boiling point. With 180F between freezing and boiling that means each degree Celsius is 1.8 degrees Fahrenheit.

Here's s a simple guide to what affects the time it takes for water to boil, and the usual time different volumes of water boil.

Despite being nonpolar, the trans isomer of 1,2-dichloroethane has a higher melting point (−50 oC) than the cis isomer (−80 oC) because of higher symmetry which allows for compact packing in the solid phase. In contrast, the cis isomer is a polar molecule with a higher boiling point (60 oC vs 48 oC ) because of the net molecular dipole moment and intermolecular dipole-dipole interactions.
