variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces changes of state without temperature change‚ while sensible heat produces temperature change heat‚ energy that is transferred from one body to another

endothermic reactions occur. Entropy Entropy (S) is a measure of the disorder (or chaos or randomness) of a system. The entropy of the universe is increasing. Things become more stable when they become more disorderd (Second Law of Thermodynamics for the Physicists!) Think of a typical teenage bedroom: Question Can you think of other everyday examples where there is a high entropy? See powerpoint slides Entropy measures how much the energy of motion of the particles
