the laboratory thermometer
and
clinical thermometer?​

Answer 1

Answer:

Hii Mate ✌

GENERAL INFORMATION :

Thermometer : An instrument used to measure temperature.

Clinical Thermometer : Thermometer used for clinical purposes only generally for measuring human body temperature.

Laboratory Thermometer : Thermometer used for measuring temperatures of non-clinical purposes.

HERE THE REQUIRED ANSWER GOES :

Similarities between a Clinical Thermometer and a Laboratory Thermometer :

• Both are made of glass and consist of long narrow glass tube.
• Both of them have a bulb at one end.
• Bulbs of both the thermometers consist of mercury.
• Celsius scale is present in both the thermometer.

Differences between a Clinical Thermometer and a Laboratory Thermometer :

Clinical Thermometer       Laboratory Thermometer

1) Temperature range        1) Temperature range

  is 35°C to 42°C.                 is -10°C to 110°C.

2) Used to measure           2) Used to measure

Similarities:

(i) Both clinical and laboratory thermometers have long, narrow, uniform glass tubes.

(ii) The bulbs of both the thermometers have mercury in them.

Differences:

(i) The temperature range of clinical thermometers is from 35°C to 42°C while that of laboratory thermometer is from −10°C to 110°C.

(ii) Clinical thermometer is used to measure the temperature of a human body. However, laboratory thermometer cannot be used to measure the temperature of a human body.

(iii) The least count of both the thermometers differs.

(iv) Unlike clinical thermometer that can be tilted, laboratory thermometer is kept upright while reading the temperature values.
