What is the relationship between the number of gas molecules and pressure? Is it direct or inverse?
Thank you so much!!
Homework Answers
Ans :
As the number of gas particles increase the pressure of the gas also increases , and if the number of particles decrease , the pressure also decreases. So it is basically a direct relationship.
It can be given by the ideal gas law :
pV = nRT
where p is pressure , V is volume , n is number of mol ( representing number of particles) , R is ideal gas constant and T is Temperature.
