Scotch bonnet Fresh, ripe Scotch bonnets can change from green to yellow to scarlet red; however, other varieties of this pepper can ripen to orange, yellow, peach, or even a chocolate brown. Scotch bonnet Scotch bonnet, also known as bonney peppers, or Caribbean red peppers, is a variety of chili pepper named for its resemblance to a tam o' shanter hat. It is native to the Caribbean islands and Central America. Most Scotch bonnets have a heat rating of 80,000–400,000 Scoville units. For comparison, most jalapeño peppers have a heat rating of 2,500 to 8,000 on the Scoville scale. However, completely sweet
Scale of temperature and has simple relation with microscopic quantities like the average kinetic energy of particles (see equipartition theorem). In experiments ITS-90 is used to approximate thermodynamic scale due to simpler realization. Lord Kelvin devised the thermodynamic scale based on the efficiency of heat engines as shown below: The efficiency of an engine is the work divided by the heat introduced to the system or where w is the work done per cycle. Thus, the efficiency depends only on q/q. Because of Carnot theorem, any reversible heat engine operating between temperatures "T" and "T" must have the same efficiency, meaning, the efficiency
