Here is the question: Two gas containers with volumes of 100 cm3 and 1000cm3 respectively are connected by a tube of negligible volume, and contain air at a pressure of 1000 mm Hg. If the temperature of both vessels is originally 273 K, what is the new pressure when the temperature of the smaller is raised to 373 K? Answer : 1025 mm Hg How are u going to work this out this quetion? and please give some comment on my working. I got my answers correct but i have a little doubt on my working, i used initial PV/T + PV/T = final PV/T + PV/T since mass is conserved. Thx.
