In electronic circuits it is not unusual to encounter currents in the microampere range. assume a current, due to the flow of electrons. what is the average number of electrons per second that flow past a fixed reference cross section that is perpendicular to the direction of flow?

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?
