Answers
Answer:
1. laboratory thermometer- laboratory thermometer is a type of thermometer which has markings from 0 degree to 150 degree.
2.Clinical thermometer- Clinical thermometer is a type of thermometer which has markings from 35 to 42 degree Celsius.
The similarity and difference between the laboratory thermometer and clinical thermometer are as follows :-----
The clinical thermometer is a specially designed and calibrated thermometer to measure our body temperature search thermometer is known as clinical or doctors thermometer. The clinical thermometer differ from an ordinary laboratory thermometer in two respects :
(i) It is calibrated from 35°C – 42°C only. This is so because this is the range over which the temperature of the normal human body can vary.
(ii) It has a slightly bend or king in Its capillary tube. This king is given the name 'Constriction'.
The Constriction ensure that the Mercury thread does not fall back by itself after this thermometer has been used to measure the temperature of a person which can read the temperature of a person and therefore can be taken conventienly. This would not be the case if any ordinary laboratory thermometer was used for this purpose. Whereas The laboratory thermometer is used for measuring the temperature that the substance is in which degree , it is calibrated from -10° – 110°.
