Temperature is a physical quantity that expresses the hotness of matter or radiation.
Temperature drop (T1 −T 2) is a direct indication of energy extracted.
For a given resource, it is dependent on T 2 which is in turn dependent on the minimum temperature of the process T1
when the thermal conductivity is low and the coefficient of thermal expansion is large. In unsteady heat-exchange processes the maximum possible temperature drop usually determines the maximum rate at which heat exchange can occur.
A drop of 17 degrees means subtract 17 from given temperature
Complementary angles are those angles whose sum is 90°.
Let angles be x and y. x + y = 90° x : y = 2 : 3 _____ 3 * x = 2 * y 3x = 2y x + y = 90° _____ x = 2/3*y x + y = 90° 2/3y + y = 90° 2/3y + 3/3y = 90° 5/3y = 90° 5y = 90° * 3 5y = 270° y = 54°
