Compléter Heat and temperatureVersion en ligne Heat and temperature for 2nd ESO par José Vicente Pacheco 1 THERMAL different colder Celsius ENERGY boiling Kelvin movement energy kinetic Fahrenheit gives thermometers temperature energy melting HEAT forces warmer average is the energy that is transferred from a hot body to a cold one . is the energy that a body has due to the movement of its particles . INTERNAL ENERGY is all the energy that a body has due to the of its particles and the between them . TEMPERATURE is a measurement of the of all particles of the system . THERMAL EQUILIBRIUM : When two bodies at temperatures are in contact , the hot one to the cold one . As this happens the hot body gets and the cold one gets . This process ends when both bodies are at the same . This state is called thermal equilibrium . We use for measuring temperature . Thermometers are built taken into account two phenomena that occur always at the same temperature . Typically they are ice and water . There are three scales to measure temperature : , the most used one in Spain , , wich is used in the UK , and , also called absolute temperature .
