What is Temperature?
Temperature is quantitative measure of hot and cold. Or a measure of kinetic energy or thermal energy of the atoms in an object. It represents how much vibrational energy exists in the molecules of a liquid or solid, or the translational energy (speed of movement) of molecules in a gas. Temperature is measured by thermometer in our daily life and to measure high temperature the thermos couples are used. Temperature is often united by degree Celsius (°C). also sometimes Fahrenheit scale (denoted °F), and Kelvin scale (denoted K) are used. The Kelvin scale is widely used in science and technology. Celsius are widely used units in daily life. The kelvin (with a lower case K) is the unit of temperature in the International System of Units, in which temperature is one of the seven fundamental base quantities.In this, 0Kelvin says about the internal thermal energy of the substance is zero. The freezing point of water is at 273.15 K, and the boiling point of water is 373.15 K.
