Gas Laws Resources

A sample of gas under a pressure of 22.0 kPa has a volume of 33.0 cm3. The pressure is increased to 888 kPa, while the temperature remains constant. What volume will the gas occupy at this pressure...

The pressure exerted by a gas is 45.0 atm while it has a volume of 475350 cm3. What would be the volume of this sample of gas at standard atmospheric pressure?   must show units, and...

answers must show units, and must be rounded to the correct number of significant digits. Pressure for STP in atmospheric units (atm) is 1.0, STP for kilopascals (kPa) is 101.3 kPa The pressure...


Ideal Gas Law Written by tutor Dave D. In order to discuss the Ideal Gas Law, we might start by discussing matter. Matter primarily comes in three different phases. 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


Graham's Law Written by tutor Sharon Y. Graham’s Law is a law that is applied very often in chemistry and physics. 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
