Which of the thermometers A or Swill show a greater rise in temperature? LABORATORY THERMOMETER :- Friday, December 1, 2017 RAVI PRAKASH SINGH 12 A laboratory thermometer has a long narrow glass tube. Maximum minimum thermometer. A laboratory thermometer is recognizable by its long stem with a silver bulb at the end. A device which is used for measuring the temperature in a science laboratory is called a laboratory thermometer. A laboratory thermometer is a tool used in laboratories to measure temperature with a high level of accuracy. This thermometer is made up of a long glass tube having a thin bore. While laboratory thermometers are intended to support a wide array of research activities, clinical thermometers are made for health care purposes. Due to the absence of the kink, these laboratory thermometers are used in a continuous process and need to be monitored all the time to get accurate results. It can measure the temperature from -10 o C to 110 o C. Give reason for your answer: [NCERT Exemplar] Answer: The basic laboratory thermometer is similar to the clinical thermometer except that the laboratory thermometer does not have any kink. The range of a laboratory thermometer is generally from - … Figure 2 Laboratory thermometer. Clinical Thermometer Laboratory Thermometer; Clinical thermometer is scaled from 35°C to 42°C or from 94°F to 108°F. Mercury level does not fall on its own, as there is a kink near the bulb to prevent the fall of mercury level. Laboratory thermometer. Laboratory thermometer is generally scaled from -10°C to 110°C. A laboratory thermometer A is kept 7 cm away on the side of the flame while a similar thermometer B is kept 7 cm above the flame of a candle as shown in figure. The graduation marked on the tube of a laboratory thermometer can measure the temperature from -10°C to 110°C, this is known as the range of a laboratory thermometer. The laboratory thermometer is used to find out the temperature of the other objects such as water rather than human body temperature. It can be partially or fully immersed in the substance being measured. It has a scale marked in °C (degree Celsius). Laboratory thermometer. Digital thermometers do not use mercury and hence safe to use. It has a bulb at one end containing mercury. Laboratory thermometer is used to measure the temperature of things other than human body.
