From cold to hot.
It is important how heat flows because if heat didn't flow the way it does it would be to cold and we wouldn't be here.
when heat flows Out of a system
High temperature always flows to low temperature, never the other way around.
heat
heat flows from a warmer object to a cooler object.
Heat is energy and cannot be negative, If you are talking about heat flow then if you define outflow to be negative then inflow is positive.
The air flows into the furnace through the return ducts, gets heated by the furnace, and then flows out through the supply ducts to heat the home.
High temperature always flows to low temperature, never the other way around.
Heat flows from hot to cold. This is because molecules spread around and it goes from hot to cold until thermal equilibrium is reached.
heat. apex.
Heat flows towards cold.
Energy flows through organisms and the environment in the form of sunlight, which is captured by plants through photosynthesis. This energy is transferred through food chains as organisms consume each other. Eventually, this energy flows out of the biosphere as heat.
