It is developed for measuring the human body temperature. Science Class 7 – Chapter 4 ... Q1. It is a mathematical representation of heat. Thermometer (thermos: hot; metron: measure) is the universal instrument used to measure temperature. Class 7 Chemistry Heat: Types of thermometers: Types of thermometers. Clinical thermometer is used to measures the human body temperature. Temperature and heat are two words that often confuses people. Thermometers can be classified as follows: Clinical thermometer . What is the measure or basis for that hotness?
Hence, the clinical thermometers have the range 35˚C to 42˚C. Digital thermometer. It has a kink which prevents the mercury to fall down on its own.The clinical thermometer consists of a glass stem on which readings are marked.
Jul 09, 2020 - Clinical Thermometer - Heat - CBSE Class 7 Science Class 7 Video | EduRev is made by best teachers of Class 7. This video is highly rated by Class 7 students and has been viewed 1199 times. For the first time I am watching education with visualising. The answer to that is temperature.
It has bulb which contains mercury. We use a device called thermometer to measure the temperature of any object.By definition, the temperature is the measurable extent of hotness or coldness. Clinical thermometers are meant for clinical purposes.
On the other hand, Temperature is the measure of that heat. For example, how do you explain the hotness of an object? The clinical thermometer consists of a glass stem on which readings are marked. State similarities and differences between the laboratory thermometer ad clinical thermometer. Since mercury is a toxic element, thus these thermometers have been replaced by digital thermometers nowadays.Since clinical thermometers can’t be used to measure temperature other than the human body, we need a special type of thermometers for other purposes. Class 7 Chapter 4 Heat Part 2 Clinical Thermometer - YouTube There are different units to measure temperatures, like Celsius (˚C), Kelvin (K) and Fahrenheit (˚F).There are different types of thermometers according to their needs. Heat is a form of energy and its unit is Joules. It is a long narrow glass tube with a bulb containing mercury at the end. Answer-Similarities between laboratory thermometer and clinical thermometer-Both are made of glass and consist of a long narrow uniform glass tube. The scale on the thermometer is markrd from 95 F to 110 F (35 C to 43 C).The normal body temperature is shown by a red arrow at 98.4 F (or 37 C). You can use a laboratory thermometer for checking the temperature of a solvent but not a clinical one.What an app this is, mind blowing. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. Digital thermometers are an advance to the existing clinical thermometers; It is developed for measuring the human body temperature. Offered for classes 6-12, LearnNext is a popular self-learning solution for students who strive for excellenceWhat's the difference between clinical and laboratory thermometersState two differences between a laboratory thermometer.Give the reason for each differenceWhat is the relation between the Celsius scale and the Fahrenheit scale ?Which is tha faster mode of heat transfer _conduction,convection,or radiation? It is used to measure the temperatures in school or other laboratories for scientific purpose as they measure temperatures to a range higher than clinical thermometers. The normal human body temperature is 37˚C; which can fluctuate between the ranges 35˚C to … The stem consists of a thin capillary tube at the end of which there is a bulb containing mercury. Available for CBSE, ICSE and State Board syllabus. The capillary tube has a kink near the bulb which prevents the mercury from flowing back into the bulb when it is taken out of the patient's mouth. Clinical thermometers are meant for clinical purposes. The scale on the thermometer is markrd from 95 F to 110 F (35 C to 43 C).The normal body temperature is shown by a red arrow at 98.4 F (or 37 C). This means, if the heat is more, the temperature is more as well. Class 7 Chemistry Heat: Laboratory thermometer: Laboratory thermometer. It is a long narrow glass tube with a bulb containing mercury at the end. The level of mercury tells our body temperature in ˚C. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances. It ranges from -10˚C to 110˚C. Clinical thermometer can never be used for measuring the temperature of any object other than human body. The clinical thermometer has range of 35 c to 42 c . Clinical Thermometer. The normal human body temperature is 37˚C; which can fluctuate between the ranges 35˚C to 42˚C. But how do we measure temperature?
