Arrange the following steps in properr sequence for the construction and calibration of celsium thermometer. (a) Lower fixing point is marked by immersing the bulb of the thermometer in melting ice taken in a funnel. (b). The distance between the two fixed points is called fundamental interval. It is divided into 100 equal divisions in Celsium scale. (c). Take a thick walled capillary tube with thin walled glass bulb and fill it with mercury with the help of a funnel. (d) mark the upper fixing point with the help of hypsometer. (e) Place the glass bulb in a hot oil bath while filling the mercury to remove the air bubbles.

Answer» c a d e b c e a d b c e a b d c d b e a Solution :The construction and calibration of a celsius thermometer involves the following STEPS. TAKE a thick walled capillary tube with thin walled glass bulb and fill the bulb with mercury using a funnel (c) from one end and while filling it with the mercury PLACE the glass bulb in a hot oil bath to remove the air bubbles (e), now mark the lower fixing POINT by placing the bulb in melting ice taken in a funnel (a). Mark the upper fixing point with the help of hypsometer. (d). The distance between the two fixed poitns is called fundamental interval. in celsium scale the fundamental interval is divided into 100 equal divisions and it is calibrated (b).
