Heat study of thermal science1.1 TemperatureTemperature is the measure of hotness and coldness of an object.[However, coldness and hotness depends on our objective sense. Therefore, we should defne temperature in another subjective way]!amples of temperature"ody temperature # $oom temperature # %un&s surface temperature # arth&s core temperature # 'eltin( point of water # "oilin( point of water # 1.1.1 Temperature %caleTemperature scale is obtained by choosin( two f!ed pointsThere are two common temperature scale.)ne is *elsius scale.
