The pressure of an ideal gas filled in the bulb
of a constant-volume gas thermometer at 7°C is
60 cm of mercury. What will be the pressure of the
same volume of gas at 147°C?

Answer:
P1/T1=P2/T2
Explanation:
Taking volume remains constant
P1= 60 cm. P2= ?
T1= 7+273K= 280K
T2= 147+273K=420K
A.T.P
P1/T1=P2/T2
60/280=P2/420
60*420/280=P2
P2=90cm
Pressure for 147°C for same volume is 90cm
