They pant.
Both hair and feathers control the flow of heat. Without either, an animal would lose heat much quicker.
to dissipate heat.
It's round about a half hr or it'll over heat.
Heat control is by air flow control doors in the a/c and heater box. There is no water valve.
No, heat does not flow indefinitely. Heat stops flowing the temperatures are equal.
Heat flow's from cooler objects.
Apparently No, heat flow in oceanic crust is higher than continental crust
negative heat
Heat flow is made by conduction, convection or radiation.
heat flow and waves
Interatomic separation causes heat to flow slowly. As there will be time involved in transferring heat at a gap.
Flow control valve that will over come stratification of hot water flowing through the system until a circulator comes on
