An electrical resistance coil is placed inside a cylinder with adiabatic walls fitted with a frictionless piston and containing an ideal gas. A current of 5 A is maintained through the resistance, across which there is a voltage drop of 100 V. The piston is opposed by a constant external force of 1067 N . a ) Is the electrical energy transferred to the gas as heat or work, explain why ? b)at what speed must the piston move outward for the gas temperature to be constant?
