What Is The Function Of Thermometer?
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.Jun 30 2014
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 the function of thermometer in laboratory?
Laboratory thermometers measure temperature with a high level of precision for applications such as experiment monitoring instrument calibration materials testing and maintaining a sterile work environment.
What is a thermometer short answer?
A thermometer is an instrument for measuring or showing temperature (how hot or cold something is). One type of thermometer is a narrow concealed glass tube containing mercury or alcohol which extends along the tube as it expands. Another type is a digital thermometer which uses electronics to measure temperature.
Where are thermometers used?
What are the three uses of a thermometer?
– To measure the outdoor temperature. – To measure body temperature during a physical exam at the doctors. – To measure body temperature when someone is ill to determine if he/she has a fever. – To measure the temperature of an oven.
What are the features of thermometer?
What are 3 types of thermometers?
- Axillary Thermometers (under your arm)
- Oral Thermometers (under your tongue)
- Tympanic Thermometers (in your ear)
- Rectal Thermometers (in your rectum)
- Temporal Artery or Infrared Thermometers (across your forehead)
How do we define temperature?
Temperature is the measure of hotness or coldness expressed in terms of any of several scales including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e. from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).
What is laboratory thermometer answer?
Laboratory thermometers are devices used to measure temperature. There are many types of lab thermometers such as differential mechanical logging etc. Laboratory thermometers are progressively providing digital reading displays and are input-capable to computer and software programs for logging purposes.
How do body thermometers work?
What is your normal body temperature?
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
Why mercury is used in thermometer?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. … It also has a high boiling point which makes it very suitable to measure higher temperatures. Also it has a shiny appearance and doesn’t stick to the glass surface of glass.
What are the advantages of thermometer?
| advantages | disadvantages |
|---|---|
| cheap | display is harder to read |
| durable | does not work below -39 C (Hg freezing pount) |
| accurate | cannot be used for thermograph |
| easily calibrated | slow response |
What are the 4 types of thermometers?
- Digital thermometers. …
- Ear (or tympanic) thermometers. …
- Infared thermometers. …
- Strip-type thermometers. …
- Mercury thermometers.
What are the characteristics of a good thermometer?
- high thermal capacity.
- easy readability.
- high sensitivity.
What temperature is a fever?
The following thermometer readings generally indicate a fever: Rectal ear or temporal artery temperature of 100.4 (38 C) or higher. Oral temperature of 100 F (37.8 C) or higher. Armpit temperature of 99 F (37.2 C) or higher.
What are the two main types of thermometer?
Answer: two types of thermometers namely clinical thermometer and laboratory thermometer. Clinical thermometers are meant for clinical purposes. It is developed for measuring the human body temperature.
Which is the best thermometer?
- Best Overall: iHealth No-Touch Forehead Thermometer.
- Best Forehead: Ankovo Touchless Thermometer.
- Best Ear: Braun Digital Ear Thermometer.
- Best Oral: Boncare Digital Oral Thermometer.
- Best Rectal: FridaBaby Quick-Read Digital Rectal Thermometer.
What is the importance of temperature?
Temperature plays a crucial role in medical care (both humans and animals) food beverages and agriculture. Our overall health is often reliant upon temperature in many ways as well. Maintaining proper temperature levels in medical cold storage areas is critical.
What is temperature called?
Temperature is a measure of the average kinetic energy of the particles of a substance. The higher the temperature of an object the higher is its kinetic energy. … The units that are used to measure temperature are called degrees.
What does a thermometer actually measure?
What is difference between laboratory and clinical thermometer?
A clinical Thermometer is meant for clinical purposes. It is developed for measuring the human body temperature. A laboratory thermometer which is colloquially known as the lab thermometer is used for measuring temperatures other than the human body temperature.
Which thermometer is used in laboratory?
Liquid in glass thermometers
A liquid in glass thermometer is the most commonly used temperature measuring device used in laboratories. This thermometer has a glass bulb attached to a sealed glass tube known as the stem or capillary tube.
Is thermometer a computer?
A thermometer is a simple analog computer. … Although special-purpose complex analog computers are built almost all computers are digital.
What is the working principle of digital thermometer?
Digital thermometers contain a small computing mechanism and a resistor. A change in temperature causes the sensor to notice a change in resistance. The computer converts the difference in resistance into a difference in temperature and offers a digital readout in degrees.
What temperature is hypothermia?
Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia (hi-poe-THUR-me-uh) occurs as your body temperature falls below 95 F (35 C).
Is 100.9 a fever?
Everyone’s body runs at a slightly different normal temperature but the average is 98.6 degrees Fahrenheit and anything above 100.9 F (or 100.4 F for children) constitutes a fever. While a fever might be uncomfortable (and even slightly worrisome) it’s not inherently bad.
What causes hypothermia?
Why alcohol is used in thermometer?
Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. … If it freezes it won’t move in the tube so a liquid must be used that has a freezing point that’s lower than the temperature it’s measuring.
