What is the difference between boyls law and Charles law?

Answer 1

Charles's Law states: At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in Kelvin) increases or decreases. Volume /temperature = K (constant)

Boyle's Law states: Boyle's law states that at constant temperature, the absolute pressure and the volume of a gas are inversely proportional. Pressure Volume= K (constant)

It can also be stated this way: Forcing the volume V of a fixed quantity of gas to increase, while keeping the gas at the initially measured temperature, the pressure P must decrease proportionally. Conversely, reducing the volume of the gas increases the pressure.

These are gas Laws Scuba divers must know.
