It flows from Up to Down most teachers get it wrong
when heat flows Out of a system
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.
heat flows from a warmer object to a cooler object.
heat
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.
heat. apex.
In most cases it is found as heat.
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.
When heat flows into a system, its value is positive, indicating an increase in the system's internal energy. Conversely, when heat flows out of a system, its value is negative, reflecting a decrease in the system's internal energy. This convention is used in thermodynamics to describe energy transfers.
Heat flows from warmer to cooler.
