A laboratory thermometer, sometimes referred to as a lab thermometer, is a device that is used to measure temperatures other than those of the human body.
Heat
Heat is the energy delivered from one body to another as a response of a temperature differential. When two bodies of differing temperatures come together, energy is transferred—that is, heat passes the hotter to the colder.
Temperature
Temperature is a metric for determining how hot or cold something is. Degrees Celsius ℃ and degrees Fahrenheit (℉) are often used to express temperature. A thermometer is an instrument for determining temperature. Thermometers are tools used to measure the temperature of a system. A volume of mercury expands into a capillary tube when heated, making a standard thermometer.
Types of temperature scale
Temperature scale can be classified as
Fahrenheit Scale
In the United States as well as several parts of the Caribbean, the Fahrenheit scale is the most widely used method of temperature measurement. It was developed in the early eighteenth century by German scientist Daniel Gabriel Fahrenheit, who modified its measurement standards from a prior scale developed by Ole Roemer. The temperature of water is 32℉ whenever it freezes and 212℉ whenever it boils. Negative temperatures, below 0 degrees Fahrenheit, are also included in the Fahrenheit temperature scale. Absolute zero, 0 or-459.6℉ , is the lowest temperature achievable.
Celsius Scale
Beyond the United States, the Celsius system is used to measure temperature. In the 18th century, two variants of the Celsius scale were developed: the first by Swedish scientist Anders Celsius and another by Frenchman Jean Pierre Cristin. The Celsius scale is also known as the centigrade scale since it is based on a 100° variation between the freezing and boiling points of water: water freezes at 0℃ and boils at 100℃. Each degree of Fahrenheit is 1.8 times the size of a degree Celsius due to the arrangement of the boiling and freezing temperatures.
Kelvin Scale
The British physicist William Thompson, afterwards Lord Kelvin, converted the Celsius scale into the Kelvin scale in the 19th century. Kelvin was created with the goal of setting the temperature scale’s zero point at absolute zero. As a result, absolute zero is 0K, as Kelvin does not employ degrees in its nomenclature. By adding a Celsius temperature with 273.15, you may convert it to Kelvin. Kelvin temperature is broadly applied in scientific computations and calculations by its direct relationship to absolute zero. The ideal gas law, for example, employs Kelvin since its standard unit to depict the relationship between mass, pressure, temperature, and volume.
Rankine Scale
The Rankine scale gives an absolute zero-based comparable to the Fahrenheit scale, albeit it is not generally utilized outside of specific US engineering fields. The scale was developed in the 19th century by Scottish physicist William John Rankine, soon after the Kelvin scale was developed. By adding 459.67 to the Fahrenheit temperature, you may convert it to Rankine. At 0 degrees Rankine, absolute zero is therefore found. At 491.67 degrees Fahrenheit, water freezes and at 671.67 degrees Fahrenheit, water boils.
Thermometer
Thermometers are instruments that measure the temperature of a system. A volume of mercury expands into a capillary tube as heated, making a standard thermometer. If a thermometer is in thermodynamic equilibrium with an item, the temperature can be calculated from the scale.
Types of Thermometer
The temperatures of various objects, like air, human bodies, food, and a range of other things, are measured using various types of thermometers. The various types of thermometers accessible include clinical thermometers, laboratory thermometers, Galileo thermometers, maximum-minimum thermometers, and digital remote thermometers. The most commonly used thermometers are clinical thermometers and laboratory thermometers.
Clinical Thermometer
These thermometers assess the temperature of the human body at home, in clinics, and in hospitals. If the thermometer is taken out of the patient’s mouth, which has a kink that prevents the mercury from returning to the bulb, allowing the temperature to be easily recorded.
Laboratory Thermometer
Lab thermometers are used to measure the temperature in schools and other laboratories for scientific research. They are mainly employed in the industry since clinical thermometers can’t record higher temperatures. The Celsius scale of a scientific thermometer goes between 10 to 110℃
