Climate change is causing the average annual temperature to increase. birds that have adapted to temperatures in their environment must find a way to adapt. if temperatures warm up due to human activities, which adaptation are the birds most likely to make?

Why do electron microscopes have higher resolving power than light microscopes?

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.
