1.	A thermometer is taken from the melting ice into a warm liquid which results in rise in mercury level to 1/5thof the distance between the lower and the upper fixed points. Calculate the temperature of liquid in kelvins.
Answer» Solution : If the distance between the lower and upper FIXED POINTS is 1 UNIT, then Rise in mercury level =`1/5`UNITS `(1/5 - 0)/(1 - 0) = (T_C - 0)/(100)` ` rArr T_C = 20^@C` or`T = 20 + 273.15 = 293.15K`
