What is a function of thermometer?
A thermometer is a device used for measuring temperature. A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air.
What is the function and uses of thermometer?
A thermometer is a tool that measures temperature — how hot or cold something is. Thermometers are used to see if you have a fever or tell you how cold it is outside. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward.
What is laboratory thermometer answer?
A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C. Laboratory thermometers are designed for lab purposes such as checking boiling point, freezing point, or temperature of other substances.
What thermometers are used in labs?
With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature. Mercury thermometers are used in households, laboratory experiments, and industrial applications.
What is the working principle of thermometer?
These liquid thermometers are based on the principal of thermal expansion. When a substance gets hotter, it expands to a greater volume. Nearly all substances exhibit this behavior of thermal expansion. It is the basis of the design and operation of thermometers.
What is digital thermometer short answer?
The Digital Thermometer is a battery-operated thermometer with connected measuring sensor and easy to read LCD display.It generates great accurate temperature readings.It is made of durable plastic materials and suitable for all kinds of refrigerant equipments such as refrigerant cabinet, display cabinet and so on.
What is laboratory thermometer Ncert?
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. One such thermometer is known as the laboratory thermometer with a scale generally ranging from –10°C to 110°C.
What is lab temperature?
Most laboratories’ room temperatures fluctuate between 20 and 25 °C [13]. Room temperature and ambient temperatures are directly affected by the heating and cooling system. Due to air flow patterns, hot and cold spots occur in the laboratory [13].
How do you use a lab thermometer?
Use of Laboratory Thermometer:
- Take some water in a beaker.
- Take a laboratory thermometer and immerse its bulb end in water, holding it vertically. Ensure to dip whole portion of bulb end.
- Observe the movement of rise of mercury.
- Repeat this with hot water and take the reading.
What are the functions of the parts of the thermometer?
The available thermometer parts and function have the ability to record temperatures unaided using sensors that record the surrounding conditions. The multifunctional thermometer parts and function are capable of recording heat and humidity changes of the surrounding areas.
What is the purpose of a thermometer?
Thermometers are normally used to measure the temperature of one’s body. This device is traditionally found in clinics, hospitals, pharmacies and homes for this purpose. It helps in recording the temperature of the body at different times, in case of fever caused by various types…
What are the uses of thermometer?
Uses of thermometer. As we established, the main use of thermometer is to measure temperature. You can measure the temperature of many things to get useful information about your surroundings and yourself.
What can a thermometer do?
A thermometer measures heat. With two important elements, the sensor and the reader, a thermometer can measure a physical change in temperature and convert that change into a value that is easily understood.
