I want to determine the pressure rise occurred in a room of a volume V by pumping more amount of air into the room without a way for the air to go out. Are there any formulas to measure this pressure Rise. Please Help me......
Sure....assuming that the pressure increase resulted in negligible temperature increase then P1 = M1*V1, where M1 is the initial mass, P1 is the initial pressure, and V1 is the initial volume.
If you know P1 and V1 then the thing you can measure is the mass. Realistically that is going to be unrealistic.
If you are going to pump more air (i.e. more mass) into an air tight room, then the pressure will be a function of the increased mass and volume. More than likely, this homework will probably have the units of measure for the volume of gas to be pumped into the room as something like X liters. Then all you need to do is to determine the mass of X liters and do the algebra.
