They are solids, liquids and gases. * Each of these three phases have their own distinct characteristics. A good introductory exercise to talking about this subject would be to, on a sheet of paper, make three lists of characteristics... read more

This law was formulated in 1846 by Thomas Graham, a physical chemist, and applies only to gases. It states that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles, as shown in the following equation: First,... read more
Gas Laws Gas has existed since the beginning of time; oftentimes, it was referred to as “air” or “oxygen;” however, in the late 18th century, “air” became known as gas, and people were able to distinguish between different types of gas. Towards the end of the 18th century, scientists started testing and developing laws that later became known as the “gas laws.” These laws describe properties... read more
