What is a thermometer answer?
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 the 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 thermometer and types of thermometer?
A thermometer is a device that is used to measure the temperature of a body. Common types of thermometers are Medical thermometers, Infrared thermometers, Mercury thermometers, thermocouple thermometers, laboratory thermometers, Bimetallic strip thermometers, Pyrometers, etc.

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 kind of temperature does a thermometer measure?
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. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system.
Can a liquid thermometer measure the temperature of alcohol?
Liquid thermometers can be limited by the type of liquid used. Mercury, for instance, becomes a solid at -38.83 degrees Celsius (-37.89 degrees Fahrenheit). Mercury thermometers cannot measure temperatures below this point. Alcohols, such as ethanol, boil at about 78 degrees Celsius (172 degrees Fahrenheit).
How is temperature defined as a physical quantity?
Temperature is operationally defined to be what we measure with a thermometer. (Many physical quantities are defined solely in terms of how they are measured. We shall see later how temperature is related to the kinetic energies of atoms and molecules, a more physical explanation.)
Why are old thermometers not registering the temperature?
Old thermometers were all non-registering thermometers. That is, the thermometer did not hold the temperature reading after it was moved to a place with a different temperature. Determining the temperature of a pot of hot liquid required the user to leave the thermometer in the hot liquid until after reading it.
