.
The volume V of a given mass of gas varies directly as the temperature T and inversely as the pressure P.
A measuring device is calibrated to give V=410 in^3 when T= 530 degrees and P=22 lb/in^2.
What is the volume on this device when the temperature is 260 degrees and the pressure is 25 lb/in^2.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The condition states this relationship between V, T and P in the form
V = , (1)
where k is the proportionality coefficient.
You also are given that
410 = . (2)
From (2), find k = and substitute it into the general formula (1) to find V at new conditions:
V = .
