Design an experiment to show that the heat flow between adjacent objects of different temperatures is greater when the temperatures is greater

answer by yourhope:

d. most models represent a real-world object in a simpler way.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
