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.
How do we use a thermometer?
Place the thermometer tip under the tongue. Hold the thermometer in the same spot for about 40 seconds. Readings will continue to increase and the F (or C) symbol will flash during measurement. Usually, the thermometer will make a beeping noise when the final reading is done (usually about 30 seconds).
What is an example of a thermometer?
A thermometer is a tool to measure temperature. Examples include liquid-in-glass thermometers, spring thermometers, industrial gas thermometers, digital thermometers, and liquid crystal thermometers.
Is thermometer a machine?
A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). He invented the mercury-in-glass thermometer (first widely used, accurate, practical thermometer) and Fahrenheit scale (first standardized temperature scale to be widely used).
What are the 3 main types of thermometers for food?
Types of Food Thermometers
- Dial Oven-Safe (Bimetal)
- Digital Instant-Read (Thermistor)
- Digital Fork thermometer.
- Dial Instant-Read Thermometer (Bimetal)
What can a thermometer be used to measure?
A thermometer is used to measure the temperature of different materials or substances. It can be used for solids, liquids or even gases.
What do the markings on a thermometer mean?
2. A thermometer is an instrument we can use to measure temperature. An analog thermometer consists of a sealed tube with markings on it. These markings are increasing temperatures in Celsius or Fahrenheit. The markings on a clinical and weather thermometer are different, but they work in the same way.
How does a digital thermometer tell the temperature?
Digital thermometers are different because they use a computer chip to tell the temperature instead of mercury. You would normally have to wait three whole minutes for the mercury to heat up and give you a reading.
What kind of thermometer can you use to take your oral temperature?
Oral thermometer Oral temperature can be taken by either a digital or mercury thermometer. We’ll go over the benefits and drawbacks of mercury thermometers below. The average oral temperature reading is 98.6°F (37°C).
What is the function of a thermometer?
A thermometer is a device that measures temperature. Most digital thermometers are resitive thermal devices ( RTD ). RTDs predict change in temperature as a function of electrical resistance.
What does a thermometer do?
A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object).
What is the temperature of a thermometer?
An instrument used to measure temperature (how hot or cold a thing is), usually in the Celsius or Fahrenheit scale . This thermometer shows a temperature of 28 degrees Celsius (which is about 82 degrees Fahrenheit)
What is the measurement of a 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. The Celsius scale is part of the metric system.
