1.	A constant volume gas thermometer shows pressure readings of 50 cm and 90 cm of mercury at 0^(0)Cand 100^(0)C respectively. What is the , . temperature on gas scale when the pressure reading is 60 cm of mercury ?
Answer» Solution :GIVEN that `P_(0) = 50` cm of Hg `p_(100) = 90 ` cm of He P = 60CM of Hg t= ? `t_(C) = (P - P_(0))/(P_(100) - P_(0)) XX 100^(0 ) C ` so `t_(C) = (60 - 50)/(90 - 50) xx 100^(0) C = 26^(0) C `
