What is heat? Heat is energy transferred from one system to another by thermal interaction. It travels from a warmer to cooler region. It is different from temperature and the unit is ‘joule’. A form of energy.

Sir Benjamin Thompson Born on 26 March 1753 in Woburn, Massachusetts, died on 21 August 1814. An inventor and scientist He is known for his expertise in thermodynamics. Won the Copley Medal

His experiments Investigated insulation properties fur, wool, feathers due to convection of air Heat was not caloric, but a form of motion observing friction generated by a cannon submerged cannon barrel in water inexhaustible frictional heat Measuring heat devised method to measure heat of a solid substance however, Johan Wilcke published his discovery first

Contributions Rumford fireplace tall and shallow, reflect more heat streamlined throats – less turbulence does not carry away room air Coffee percolator water moves up the tube when heated seeps through ground coffee drips back into the brewed coffee

Contributions Thermal underwear/long johns a two-piece clothing made of cotton or wool traps body heat

Reflection Learning points think creatively learn from mistakes persevere until you succeed take risks Obstacles faced: Unable to concentrate on the task Did not understand the information online
