If you stick a metal rod in snowbank. the end in your hand soon becomes cold. Does cold flow the snow to your hand?
Cold doesn't travel, heat does. The heat travels from your hands to the snow.
Do heat and cold flow between objects?
Technically the answer to your question is no. Heat does indeed flow between objects, but cold does not because it doesn't really physically exist. "Cold" is just a lower level of heat.
Why does the heat flow into the evaporator?
The evaporator is cold.. heat flows to a colder object.
How can our body react with heat and cold?
Our bodies are perfectly normal with heat and cold at the same time. Heat increases the flow of blood while cold decreases the flow of blood, so when they are both together reacting at the same time, basically the flow of blood is going at a normal rate
Heat never of itself flows from a cold to a hot substance?
Heat can flow from cold to hot substances. It's flow depends on the total amount of heat of the substance not on the temperature. It flows from the substance which has more heat to the substance which has less heat stored in it.

What is the direction of the flow of heat?
Heat flows towards cold.

Does heat flow from a source that is warm to a source that is cold?
Heat does, indeed, go from a warm source to a cold place. That is what heat always does.
What way can heat never flow?
From cold to hot.

If you have two metallic strips one of them is cold and other is hot and if you put them in contact where will be the flow of heatGive reason also?
The two pieces of metal will try to reach equilibrium. The heat will flow from the hot one into the cold one until the two are the same temperature.
On a cold winter day the flow of heat is from the outside in?
Falseee
What factor free covection heat flow depends?
The only factor that free convection heat flow depends on is the conductivity of the material. Heat moves toward a cold area and heat it up and the reverse is true for cold, it will cool down something warm.
Is conduction of heat is a physical property?
Temperature is a physical property and it determines how hot or cold an object is. Heat flow is always from hot to cold.
