Electrons, like all other matter, exhibit the dual behavior of both and waves. Since electrons travel like waves, their energy is restricted to certain energy , each of which is associated with a specific wavelength. Listen to the complete question

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation

Critical mass is the of material required to produce a chain reaction. a.) minimum amount b.) atomic mass c.) precise amount d.) maximum amount

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
