### What is temperature Brainly physics?

Explanation. Temperature is used to measure the coldness or hotness of an object along with a standard value . It is a physical property of matter. It is measured with the help of a thermometer. It is commonly measured on the scale of Celsius ( C° ) or Fahrenheit ( F° ) or Kelvin ( K ).

Answer: Temperature is a physical quantity that expresses hot and cold . It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter.

### What are the 3 temperature names?

The three main temperature scales are Celsius, Fahrenheit, and Kelvin . Temperatures can be converted from one scale to another using temperature conversion equations.

The SI unit of temperature as per the International System of Units is Kelvin which is represented by the symbol K. The Kelvin scale is widely accepted or used in the field of science and engineering. However, in most parts of the world, Celsius or Fahrenheit scale is used for measuring temperature.Nov 29, 2020

Answer: Temperature is the degree of hotness or coldness of a place or a body . Heat Energy is the form of energy, which flows from a hot body to cold body.

The average temperature of the air as indicated by a properly exposed thermometer during a given time period, usually a day, a month, or a year . For climatological tables, the mean temperature is generally calculated for each month and for the year.Feb 20, 2012

### What is temperature and example?

Temperature is the measure of hotness or coldness of an object . Temperature can be measured in metric units or in U.S. customary units. We can use a thermometer that has both a Celsius ( °C ) and a Fahrenheit ( °F ) scale to measure the 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).

The measurement of body temperature can help detect illness . It can also monitor whether or not treatment is working. A high temperature is a fever.

In sum: writers and editors reporting Celsius or Fahrenheit should (1) close up spaces between numerals, degree symbols, and temperature units and (2) repeat the degree symbol and the unit when reporting temperature ranges . For example: 37.5°C-37.9°C.

Temperature is an intensive property. The SI unit of temperature is the kelvin (K) . The IUPAC convention is to use kelvin (all lowercase) for the word, K (uppercase) for the unit symbol, and neither the word “degree” nor the degree symbol (°).

Temperature is measured by using a device (or instrument) called thermometer . A thermometer has a scale marked on it which is used to read the temperature. The most common temperature scale marked on thermometers for measuring temperatures is the Celsius scale.

### What is temperature in science for Class 3?

Unit of temperature can be K or °C or °F . Temperature in °C = 273 – Temperature in K. 0°C = 32°F. Temperature of ice is 0°C or 32°F.

Temperature is defined as a measure of the average kinetic energy of all of the particles in a substance . The faster the particles in a substance are moving, the greater the average kinetic energy of the substance, the higher its temperature, and the warmer it feels.
