Silver is a good conductor with high electrical conductivity. The room temperature electron mobility in silver is 0.00557 mV's.The density of silver is 10.5 g/cm3. Assume that, on average, 1.3 free electrons are contributed by one silver atom for electrical conduction. Determine the number of free electrons per cubic meter for silver at room temperature. Calculate the electrical conductivity at room temperature. How will the electrical conductivity of silver be affected when the temperature is increased? Explain the reason(s)
