What is simple thermometer?
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 you make a homemade thermometer for kids?
Directions Start by asking your child to consider the weather. Pour the water into the glass bottle. Pour the rubbing alcohol into the bottle. Add a few drops of food coloring. Insert the straw into the bottle. Secure the straw with modeling clay at the top of the bottle.
How does a DIY thermometer work?
Homemade thermometer explanation: When the air inside the bottle expands, the pressure inside the bottle increases, pushing down on the liquid inside the bottle and pushing more liquid up the straw. When you cool the air again, it loses energy and decreases the pressure.
What are the 3 ways to measure temperature?
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale.
Is laboratory thermometer and simple thermometer same?
A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature.Thermometers. Clinical Thermometer Laboratory thermometer It has kink, which prevents immediate backflow of mercury It does not have a kink.
Can a smartphone be used as a thermometer?

How do you make a thermometer model for a school project?
What You Do: Put a few drops of food coloring into the water bottle and fill it to the top with lukewarm water. Insert the straw a couple inches into the bottle and mold the clay around it to seal the bottle and hold it in place. Use a marker to mark the level of the water in the straw.
What is inside the laboratory thermometer?
Liquid-in-glass thermometers are made of sealed glass and contain a fluid, usually mercury or red alcohol, whose volume changes relative to its temperature. The liquid expands as the temperature rises, rising in the tube and indicating the temperature.
How do you make a clinical thermometer?
Complete step-by-step answer: A clinical thermometer usually consists of cylindrical bulb b which usually contains mercury in it. A capillary tuber t of uniform and fine bore is attached to the bulb. Just above the bulb of the thermometer, at point c, the bulb is made to be narrow and bent.

How do you calibrate a homemade thermometer?
HOW TO CALIBRATE. A THERMOMETER. Fill a large container with crushed ice. Add clean tap water until the container is full. Stir the mixture well. Thermometers should be calibrated regularly to make sure the readings are correct. The ice-point method is the most widely used method to calibrate a thermometer.
How do you measure 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).

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. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
What do you mean by ordinary thermometer?
Both ordinary and clinical thermometers are used to measure the hotness or coldness of substances. The clinical thermometer is used to measure the body’s temp. but an ordinary thermometer is used to measure any object’s temperature.
What is normal temperature for human body?
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.
Can iPhone tell temperature?
The iPhone has temperature sensors within it, but like other smartphones, Apple uses the sensors to monitor the battery and processor’s temperature. To successfully measure air temperature, you’d need a sensor on the outside of the device, as far away from the internal components as possible.
