you are boiling water to make pasta. How could you descibribe the pot, water, and pasta using physical properties?

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.

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
