Hint: 1 choice The temperature of boiling water at standard atmospheric pressure at 100Ã??Ã?°C The temperature of pure steam from boiling water at standard atmospheric pressure, at 100Ã??Ã?°C The temperature of water at which water evaporates The temperature of the air surrounding the boiling water at standard atmospheric pressure at 100Ã??Ã?°C 3/10 The thickness or thinness of the wall of the glass bulb will _________. Hint: 1 choice Decide the heat capability of the thermometer Decide the range of temperatures that the thermometer can measure Decide the sensitivity of a thermometer Decide the efficiency of a thermometer 4/10 When calibrating a thermometer, it should be placed into Hint: 1 choice pure melting ice and steam of pure boiling water at atmospheric pressure pure melting ice and pure boiling water at atmospheric pressure melting ice and steam of pure boiling water at atmospheric pressure melting ice and pure boiling water at atmospheric pressure 5/10 Which thermometer or system was more efficient in mass-screening of patients? Hint: 1 choice Infrared thermography Digital thermometer Liquid crystal thermometer Ear Thermometer 6/10 You read a mercury-in-glass thermometer by _____, while you read other liquid-in-glass thermometers _____. Hint: 1 choice from the top of the mercury meniscus at eye level, from the top of the meniscus from the bottom of the mercury meniscus at eye level, from the top of the menisucs from the middle of the mercury meniscus at eye level, bottom of the meniscus from the top of the mercury meniscus at eye level, from the bottom of the meniscus 7/10 An unmarked thermometer is placed in steam from boiling water, and the mercury level rose to 10cm. When it was placed in crushed ice, the mercury level dropped to 4cm. The thermometer was then placed in a beaker of water at unknown temperature, and the mercury level rose to 6cm. What is the temperature of the water in the beaker? Hint: 1 choice 66.6Ã??Ã?°C 40Ã??Ã?°C 33.3Ã??Ã?°C 20Ã??Ã?°C 8/10 What is the constriction in some clinical thermometers for? Hint: 1 choice It is to prevent the liquid in the thermometer from falling back to the bulb immediately after taking the reading It is to prevent the liquid in the thermometer from rising too high It is to prevent the liquid in the thermometer from decreasing in volume from its original volume It is to ensure a smoother flow of the liquid in the thermometer 9/10 A thermometer with a longer and thicker capillary tube will be able to cover a wide range of temperatures. Why? Type answer. Hint: 63 characters 10/10 How does the size of the glass bulb affect the thermometer? Type answer. Hint: 63 characters
