Document Summary
Systems, properties, state, and processes: a large fraction of the thermal energy generated in the engine of a car is rejected to the air by the radiator through the circulating water. Assume the earth to be a perfect sphere with a radius of 6377 km, and take the thickness of the atmosphere to be 25 km. Temperature: what is the zeroth law of thermodynamics, what are the ordinary and absolute temperature scales in the si and the. English system: consider an alcohol and a mercury thermometer that read exactly 0 c at the ice point and 100 c at the steam point. The distance between the two points is divided into 100 equal parts in both thermometers. Explain: the deep body temperature of a healthy person is 37 c. What is it in kelvins: consider a system whose temperature is 18 c. R, k, and f: the temperature of a system rises by 15 c during a heating process.
