Describe the
These are a set of laws followed only approximately by real gases. The laws relate volume occupied by the gas molecules, the pressure exerted by them, the temperature at which the gas is, and the amount of the gas in terms of moles.
The nature around us is full of examples of these laws and we will take the help of these showcases to better understand the laws.
Ever wondered why an air bubble expands while ascending in a water body?
The answer lies in the fact that while we go deeper into the water the pressure keeps on increasing. Inversely, as the bubble traverse its way above, it observes a lower pressure as it rises and as a result volume of the air bubble increases.
This is exactly what is denoted in Boyle's law. It says that at a constant temperature the pressure at which the gas is inversely proportional to the volume of the gas given that the amount of the gas is the same throughout. It can mathematically be represented as follows:
This law relates the volume occupied by the gas molecules with the temperature of the system, at constant pressure and constant amount of gas. The volume and temperature of a gas are directly proportional to each other. Hot air balloons work on this principle since air at higher temperature expands and lifts the balloon up.
The mathematical representation is:
Another way of putting this forth is that the warm air expands and cold air occupies less volume.
