Gas laws - Wikipedia
Boyle's law or the pressure-volume law states that the volume of a given of gas held at constant volume is directly proportional to the Kelvin temperature. In other words according to Boyle's law volume is inversely proportional to k1 here is a proportionality constant, V is the Volume and p is the pressure. Jul 17, Gay-Lussac's Law states that the pressure of a given mass of gas A graph of pressure vs. temperature also illustrates a direct relationship.

A torr is the same unit as the mmHg millimeter of mercury. It is the pressure that is needed to raise a tube of mercury 1 millimeter.
The Pressure-Volume Law Boyle's law or the pressure-volume law states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.
Another way to describing it is saying that their products are constant.
Gay-Lussac's Law: Temperature and Pressure - Chemistry LibreTexts
When volume goes up, pressure goes down. From the equation above, this can be derived: This equation states that the product of the initial volume and pressure is equal to the product of the volume and pressure after a change in one of them under constant temperature.
For example, if the initial volume was mL at a pressure of torr, when the volume is compressed to mL, what is the pressure? Plug in the values: The Temperature-Volume Law This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature. V Same as before, a constant can be put in: Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.

The Pressure Temperature Law This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. P Same as before, a constant can be put in: The Volume Amount Law Amedeo Avogadro Gives the relationship between volume and amount when pressure and temperature are held constant.
Remember amount is measured in moles. Also, since volume is one of the variables, that means the container holding the gas is flexible in some way and can expand or contract.
If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases.
V As before, a constant can be put in: It is important to recognize the contribution of Lord Kelvin to the field of kinetics. Kelvin determined that the temperature in Celsius caused the relationships between the temperature and other variables was non-linear, but was always proportional to a single constant.
It has been theorized that the lowest possible temperature is 0K or — At this point scientists have determined that there should be absolutely no kinetic energy within a system, therefore no movement, and therefore no energy at all. This condition will probably never be realized since the natural processes that work in kinetics are always trying to move away from this temperature and would ultimately transfer energy into a system without any, negating the whole idea.
If a gas is at a static condition not being transferred from one set of conditions to another set of conditions the ideal gas law must be used.
It was found that the pressure times the volume divided by the amount of the gas times the temperature are always equal to the same value. This value was given the symbol R and is equal to 8. If you are given three of the variables you can calculate the fourth using the constant.
The ideal gas law is written as follows: Dalton discovered that the amount of a gas in a container had a direct affect on the pressure.
