In the equation P=², the P stands for pressure.
How to determine pressure?
This equation is a simplified form of the ideal gas law, which describes the behavior of gases under various conditions. The ideal gas law is:
PV = nRT
where:
P = pressure of gas
V = volume of gas
n = moles of gas
R = universal gas constant
T = temperature of gas
The equation P=² is a special case of the ideal gas law where the volume and temperature are held constant. In this case, the pressure is directly proportional to the number of moles of gas.
