temperature is a measure of effect of heat energy. It tells us about the degree of hotness or coldness of a body. Increase in volume, change in specific resistance, emmision of electro magnetic waves (like Light) are the general effects of the temperature. Based on these principles temperatures are measured. Change in volume --- Liquid thermometers -- Mercury thermometers Change in resistance --- Resistance thermometers ---- digital thermometers Emmission of E/M waves --- Radiation thermometers --- Pyrometers RAMKI--India
