I’m guessing convection currents since you mention mantle and core, reminds me of heat
Explanation:
yusef adds all of the values in his data set and then divide by the number of values in the set. the actual density of iron is 7.874 g/ml .
Refrigerant entering the compressor of a refrigeration system is sub-cooled liquid
The liquid refrigerant is sub-cooled to ensure that only liquid and not the vapour enters the throttling valve. In a refrigeration system, the superheating decreases COP increase refrigerating effect but increasing amount of work done. The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
