Relation between p, V, T, and number of moles of the gas
Methane is the gas present in coal mine.
Ideal Gas
Gas laws explain how the property of a gas changes in relation to other properties under varying conditions.
An ideal gas
Yes, the amount of gas present can affect its behavior. Increasing the amount of gas typically leads to an increase in pressure and can affect other properties like volume and temperature as described by gas laws such as Boyle's law or Charles's law. Additionally, the interactions between gas molecules can also change with variations in gas quantity.
Oxygen gas must be present for a combustion reaction to occur.
LPG contains petroleum gas.
Kelvin scale is used for correct calculations according to gas laws.
If you are absolutely certain there was no gas present tell your Doctor, its not uncommon for people with brain tumours to smell gas that is not present.
Methane
Freon
The temperature scale that must be used in all gas laws is the Kelvin scale. This is because the Kelvin scale starts at absolute zero, which is the point where particles have minimal kinetic energy, making it the ideal scale for gas laws calculations.
