900k,what is the pressure inside a container? I understand that the air pressure is proportional to both the air's density and air temperature, but I'm unsure of the calculation to determine the pressure
What is the container volume? How much is in it? Is it a gas? What does the 900k mean? Is that supposed to be the temperature? (If so, it should be written 900 K)
This is presumably an exercise in using the ideal gas law, PV = nRT, but you need more information (You need n and V). R is a constant of nature.
