what is temperature
Answers
Temperature is a physical quantity expressing hot and cold. It is measured with a thermometer calibrated in one or more temperature scales. The most commonly used scales are the Celsius scale (formerly called centigrade) (denoted °C), Fahrenheit scale (denoted °F), and Kelvin scale (denoted K). The kelvin (the word is spelled with a lower-case k) is the unit of temperature in the International System of Units (SI), in which temperature is one of the seven fundamental base quantities. The Kelvin scale is widely used in science and technology.

Answer:
Temperature is the degree of hotness or coldness of a body. When two bodies are placed in contact, the heat flows from the body at Higher temperature to the body at lower temperature. Thus temperature may be defined as the thermal state of our body which decides the direction of flow of heat energy from one body to another when they are placed in thermal contact with each other.
