Gas laws give the statement

hii dost
gas is like oxygen etc.
thx dude
plz follow
Answer:
For a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.
PV = nRT
Boyle's Law: 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.
V is proportional to the inverse of P
Another way to describing it is saying that their products are constant.
PV = C
When pressure goes up, volume goes down. When volume goes up, pressure goes down.
From the equation above, this can be derived:
P1V1 = P2V2 = P3V3 etc.
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.
Charles' Law: 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 is proportional to T
Same as before, a constant can be put in:
V / T = C
As the volume goes up, the temperature also goes up, and vice-versa.
Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.
V1 / T1 = V2 / T2 = V3 / T3 etc.
Gay-Lussac's Law: 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 is proportional to T
Same as before, a constant can be put in:
P / T = C
As the pressure goes up, the temperature also goes up, and vice-versa.
Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.
P1 / T1 = P2 / T2 = P3 / T3 etc.
Avogadro's Law: The Volume Amount Law
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 is proportional to n
As before, a constant can be put in:
V / n = C
This means that the volume-amount fraction will always be the same value if the pressure and temperature remain constant.
V1 / n1 = V2 / n2 = V3 / n3 etc.
The Combined Gas Law
Now we can combine everything we have into one proportion:
V is proportional to T divided by P
The volume of a given amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.
Same as before, a constant can be put in:
PV / T = C
As the pressure goes up, the temperature also goes up, and vice-versa.
Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.
P1V1 / T1 = P2V2 / T2 = P3V3 / T3 etc.
