The Question is in the paint document.
My question to this problem is at the bottom of thread 1
Equation:
T = T_{3}/P_{3}P. Where
T_{3} is the temperature (K) of water at triple point
I am not 100% sure what P and P_{3} stand for (can someone tell me)
I believe P is the net pressure (Pressure supplied by the bulb minus the pressure opposing the pressure supplied by the bulb)
and P_{3} is the pressure at triple point.
Solution:
All Temp are in Kelvin (K)
Define:
T_{L} = Temp of left bulb
P_{L} = Pressure of left bulb
T_{R} = Temp of right bulb
P_{R} = Pressure of right bulb
First Step:
Let T_{L} = T_{3} and T_{R} = Boiling Point of Water = (BP)
T_{L}  T_{R} = T_{3}  (BP) =
T_{3}/P_{3}(P_{L}  P_{R})
Because (T_{L}  T_{R})<0 Then (P_{L}  P_{R}) = 120torr.
Solving for P_{3}:
P_{3} =T_{3}(P_{L}  P_{R})/(T_{3}  (BP))
Second Step:
Let T_{L} = T_{3} and T_{R} = Unknown Temp. (T)
T_{L}  T_{R} = T_{3}  T = T_{3}/P_{3}(P_{L}  P_{R})
Solving for T:
T = T_{3}  T_{3}/P_{3}(P_{L}  P_{R})
QUESTION:
Because I dont know If T>T_{3} or T<T_{3} I do not know whether (P_{L}  P_{R}) = +90torr or 90torr.
How am I suppose to know?
