Answer: given Si and Cu are colled to a temprature of 300k resistivity of metall increase with temperature and rasistivity of semiconductor decreases with increasing temperature for metal , R increasing as. T increasing
For metal R decreasing as T increasing
we know Si as semiconductor and CU is an metal so as temperature Resistivity of Si increasing or Cu decrease.
Hope it help you please mark as brilliant
Have a great day ☺️
