Hi,
Can someone please tell me what I am doing wrong with the following problem. The computer keeps telling me that I am coming up with the wrong answer. In a constantvolume gas thermmoeter, the pressure at 18.0 C is 0.980 atm. What is the pressure at 42.0 C? I am using the equation (P1/T1) = (P2/T2) and I am solving for P2. (P1/T1) = (P2/T2) P2 = (P1/T1)(T2) P2 = (0.980/18.0)(42.0) P2 = 2.29 atm I know this is a really simple problem, but I just don't understand what I am doing wrong. Someone please help me.
