State similarities and differences between the laboratory thermometer and the clinical thermometer.

Answer

Similarities between laboratory thermometer and clinical thermometer are:

 1. Celsius scale is present in both the thermometers.                                                                                                                                                                       2. Both are made up of glass and consists of ling narrow tube.                                                                                                                                                     3. Both of them have a bulb at one end.                                                                                                                                                                                         4. Both contains mercury in them.                                                                                                                                                                                                   5. Both the thermometers are used to measure the temperature. 

Differences between laboratory thermometer and clinical thermometer are:

1. Clinical thermometer is used to measure the human body temperature whereas the laboratory thermometer is used to measure the temperature in the laboratory.                                                                                                                                                                                                                                        2. Clinical thermometer have temperature range between 35 - 42º C whereas the laboratory thermometer have range from -10º C to 110º C.                              3. Clinical thermometer contains kink which prevents backflow of mercury whereas laboratory thermometer does not contain kink.
