Are there different types of thermometers?
In general, there are two types of thermometers. Touch, or contact, thermometers must touch the body in order to measure temperature. Remote, or no contact, thermometers can measure body temperature without touching the skin.
How many different kinds of thermometers are there?
There are 6 kinds based on how they work.
What are the 3 types of temperature measurement?
Temperature Scales. There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin. Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts.
What is a thermometer in physics?
A thermometer is used to measure how hot or cold something is. There is a number scale showing temperature going from cold at the bottom to hot higher up. There are different types of thermometer and some are electrical.
What is thermometer and its types?
A thermometer is a device that is used to measure the temperature of a body. Common types of thermometers are Medical thermometers, Infrared thermometers, Mercury thermometers, thermocouple thermometers, laboratory thermometers, Bimetallic strip thermometers, Pyrometers, etc.
What are the two main types of thermometer?
- Digital thermometers. Digital thermometers are regarded as the fastest and most accurate type of thermometer.
- Electronic ear thermometers.
- Forehead thermometers.
- Plastic strip thermometers.
- Pacifier thermometer.
- Glass and mercury thermometers.
What are the 5 uses of thermometer?
Body temperature is measured with a medical or clinical thermometer. Laboratory thermometer is used to determine the room temperature of heated solids and liquids. Infrared thermometers can take readings from a distance. Restaurants use thermometers to monitor the temperature of the dishes for baking and cooking.
Which type of thermometer is the most accurate?
Digital thermometers are the most accurate way to measure body temperature. There are many types, including oral, rectal, and forehead, plus many that are multifunctional.
What are the three uses 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.
What thermometer is used to measure the temperature of a liquid?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
What is a thermocouple thermometer?
thermocouple, also called thermal junction, thermoelectric thermometer, or thermel, a temperature-measuring device consisting of two wires of different metals joined at each end. One junction is placed where the temperature is to be measured, and the other is kept at a constant lower temperature.
What are the 5 methods for assessing temperature?
- Rectal. The thermometer is placed in the child’s bottom.
- Oral. The thermometer is placed in the mouth under the tongue.
- Axillary. The thermometer is placed in the armpit.
- Tympanic. The thermometer is placed in the ear.
- Temporal artery. The thermometer scans the surface of the forehead.
How many types of scales are there in physics?
There are four different scales of measurement.
What is example of thermometer?
Examples include liquid-in-glass thermometers, spring thermometers, industrial gas thermometers, digital thermometers, and liquid crystal thermometers.
What is the use of six thermometer?
Six’s maximum and minimum thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. It is used to record the extremes of temperature at a location, for instance in meteorology and horticulture.
Is pyrometer a thermometer?
A pyrometer is a type of remote-sensing thermometer used to measure the temperature of distant objects. Various forms of pyrometers have historically existed.
What are the types of thermometer Class 7?
- Clinical thermometer /medical thermometer.
- Laboratory thermometer.
- Digital thermometer.
- Infrared ear thermometer.
- Mercury thermometer.
- Alcohol in glass thermometer.
- Constant pressure gas thermometer.
- Constant volume thermometer.
What is the SI unit of temperature?
The kelvin is the SI unit of thermodynamic temperature, and one of the seven SI base units. Unusually in the SI, we also define another unit of temperature, called the degree Celsius (°C). Temperature in degrees Celsius is obtained by subtracting 273.15 from the numerical value of the temperature expressed in kelvin.
What is the most common type of thermometer?
Probe thermometers are easily one of the most common types of thermometer. They deliver instant temperature readings of foods, liquids and semi-solid samples. The probe is often equipped with a pointed tip making them ideal for penetration and immersion.
Which thermometer has higher range?
Solution : Gas thermometer is more sensitive as coefficient of expansion of Gas is more than mercury. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
What type of thermometer uses mercury?
The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (1714). It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb.
How do thermometers work?
How does a thermometer tell the temperature? A thermometer measures temperature through a glass tube sealed with mercury that expands or contracts as the temperature rises or falls. The tiny size of the bulb and micro-fine size of the tube help the mercury reach the temperature of what it is measuring very rapidly.
Who invented the thermometer?
Galileo Galilei invented a rudimentary water thermometer in 1593 which, for the first time, allowed temperature variations to be measured.
What is a thermometer Class 7?
Thermometer is a device which is used to measure temperature. Thermometer is made of a long narrow glass tube, with a bulb at one end. The narrow tube appears as a continuous silver line, because it is filled with mercury.
