Heat and Thermodynamics
... Conduction is heat transfer by means of molecular agitation within a material without any motion of the material as a whole. If one end of a metal rod is at a higher temperature, then energy will be transferred down the rod toward the colder end because the higher speed particles will collide with t ...

... The external pressure can be changed in many ways. Each way will involve a different amount of work. We shall look at two ways, each of which has its own formula for calculating the work. 1) Constant external pressure, Pex This is path B in the diagram below. In a first step, the volume is held cons ...

Heat Transfer and Energy
... • Warm air is less dense than cold air at the same atmospheric pressure (Ideal Gas Law!) • Think of cold air as being heavier. Thus, when the Earth’s surface is heated by solar (shortwave) radiation, heat conduction occurs. The thin layer of air molecules at the Earth’s surface is heated through con ...

... A gun is a heat engine. In particular, it is an internal combustion piston engine that does not operate in a cycle, but comes apart during its adiabatic expansion process. A certain gun consists of 1.80 kg of iron. It fires one 2.40-g bullet at 320 m/s with an energy efficiency of 1.10%. Assume that ...
