Whether you are consciously aware of it or not, you pay attention to the temperature constantly.\u00a0 Are you too hot or too cold?\u00a0 If you touch something that\u2019s too hot, like inadvertently touching a pan that has been heated up on the stove, you pull your hand back quickly, reacting to the temperature of the pan.\u00a0 Afterwards, you might go grab a piece of ice and hold it on your hand, knowing that having the cold ice in contact with where you burned your skin will feel good.\u00a0 So, though you think about temperature every day, you probably don\u2019t have a very good definition for what the temperature means.\u00a0 You know how to measure it with a thermometer, but you may not necessarily know what that measurement is describing.<\/p>\n
Heat is another word that we use every day, but if someone asked you to explain what heat is, you might have trouble coming up with a good definition.\u00a0 In fact, the way most of us use the word heat in every day conversation is actually at odds with the way heat is defined scientifically.\u00a0 As a result, the first thing we need to do in beginning thermodynamics is understand the differences between heat, temperature, and energy.<\/p>\n\n\t\t\t Candela Citations<\/h3>\n\t\t\t\t\t
