What are the small lines on a thermometer?
On a thermometer that uses the Fahrenheit temperature scale, each long mark shows a whole degree of temperature. There are four shorter lines between each pair of long lines. These shorter lines show an increase of two-tenths of a degree Fahrenheit (0.2ºF).
What are the markings on the body of a thermometer called?
The most common temperature scale marked on thermometers for measuring temperatures is the Celsius scale. So, the temperature is expressed in the unit of ‘degree Celsius’ (which is written in short form as °C). In the unit °C, the small circle at the top denotes the term ‘degree’ and the letter C denotes Celsius.
What is the tiny tube in the thermometer?
A thermometer is the instrument used to tell the air temperature. A thermometer is usually made up of a small, hollow glass tube. At the bottom of the tube is a bulb, which holds a liquid such as alcohol or mercury. When there is an increase in heat, the liquid inside the bulb expands, pushing up into the tube.
What are the parts of digital thermometer?
It is made up of Microcontroller, memory which is embedded in the form of COB IC along with some passive components like capacitor, resistors, sensors, buzzer and switch. The analog value of temperature measured is converted to the digital form by Microcontroller and then displayed on the LCD.
What does arrow mean on thermometer?
All glass thermometers are marked with an arrow which points to 98.6 (Considered to be the normal adult temperature).
How many lines does a thermometer have?
Most thermometers have two scales for temperature, Fahrenheit and Celsius. Read the numbers for °F (degrees of Fahrenheit). Each long line is for 1°F temperature. The four shorter lines between each long line are for 0.2°F (two tenths) of a degree of temperature.
What does arrow mark on thermometer mean?
The long lines on the thermometer are one degree. All glass thermometers are marked with an arrow which points to 98.6 (Considered to be the normal adult temperature).
Why is the capillary tube of a thermometer narrow?
A glass bulb with thinner wall can transfer heat to the bulb easier. Therefore, the thermometer can response quickly to small changes of temperature near the surrounding. Capillary with narrow bore produces a greater change in the length of the mercury column.
What is present in the bulb of thermometer?
Mercury metal is used in the bulb of thermometer. This is because of its high boiling temperature and its high coefficient expansion.
What is a axillary thermometer?
An axillary (AK-sih-lar-e) temperature (TEM-per-ah-chur) is when your armpit (axilla) is used to check your temperature. A temperature measures body heat. A thermometer (ther-MOM-uh-ter) is used to take the temperature in your armpit. An axillary temperature is lower than one taken in your mouth, rectum, or your ear.
