Question

47. A faulty mercury thermometer has a stem of uniform
cross section marked in mm. If this reads 83 mm
instead of 80 mm at LFP and 229 mm instead of
220 mm at UFP, find the difference in the length of
the mercury thread in both the faulty and correct
thermometers at 250°C. (Take LFP = 0°C and
UFP = 100°C)

Asthe faulty one is showing LFP at 83mm and UFP at 229mmat temperatures 0 degree and 100 degree celciusrespectively.

soat250°Csoat250°C,

UFP shown by it is572.5mm

LFP shown by it is207.5mm

The correct thermometer will show raedings at 250 degree

UFP shown by it at 550mm

LFP shown by it at 220mm

The variations in the readings at 250 degree celcius is

UFP= 22.5mm

LFP = 12.5mm
