Thelaboratory thermometersshould be Group of answer choices shaken down before use. This is the main answer. Below of laboratory thermometers.Laboratory thermometers are devices that are utilized to measure the temperature of a substance in a laboratory.They are used in a variety of laboratory applications. These thermometers must be handled with care and kept in good working order in order to provide accurate temperature measurements.Laboratory thermometers come in a variety of sizes and shapes, each designed to meet specific temperature measurement needs. They are made of a glass tube with a bulb at one end, and are designed to be shaken down before use. This is done to make sure the mercury or alcohol is all at the bottom of the tube.Immersionof the thermometer completely in the substance whose temperature is being measured is required.The immersion must be complete and the thermometer should not touch the sides or bottom of the container. The temperature of the substance is measured when themercury or alcoholhas stabilized.Cooling the thermometer after use in cold tap water helps to reduce the stress on the glass from thermal expansion and contraction. This, in turn, helps to extend the life of the thermometer. The thermometer should be carefully handled to avoidbreakage.learn more aboutlaboratory thermometersbrainly.com/question/27892710#SPJ11...
