The second law of thermodynamics is based on the idea that heat will only spontaneously flow from a region of higher temperature to a region of lower temperature. Obviously, since we have refrigerators, we have found a way to pump heat from an area of lower temperature into an area of higher temperature by performing some work, but
#1 it requires work to make it happen - it doesn't happen spontaneously
#2 when you look at the details of the process you will always find one or more steps where heat is moving from a region of higher temperature to a lower temperature, but never a step where it moves from lower to higher.
It's just that the net effect is to move energy out of a colder region to a warmer one. The net change is always an increase in entropy

What will happen to cold-blooded animals if there is no heat energy?
They won't be able to move. Cold-blooded animals need the heat to warm them up, so they will be able to move.
When a warm front goes over a cold front?
That's called an 'occluded' front.
Does air travel from warm to cold or from cold to warm?
Cold to warm
Which can moderate climate by absorbing heatwhen the air is warm and realsing heat when the air is cold?
oceans
What are heat lamps?
It is a lamp that produces heat. Heat lamps are used to keep plants warm during cold weather. They also are helpful for warming sore body parts and for keeping you warm when you get out of the shower.
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 can warm-blooded animals do that cold-blooded cannot do?
Warm blooded animals can generate their own heat in a cold enviorment. Cold blooded animals change their temperature if they are in a cold place their body temperature changes cold if they are in a warm place it changes warm. Temperature change
What could be wrong if your 2002 alero's heater air is warm-- then goes cold--then the thermostat goes up and then the heat is warm again and the thermostat goes back down?
Souns like a head gasket to me.
Where does a banana decomposed quickly warm or cold place?
warm place
Does wind move from a warm place to a cool place?
Warm air rises over cold air when a warm and cold front connect.
What does a warm mean?
a warm mean a place that is warm not hot or not to cold.
Why would a pair of eyeglasses fog up when brought from a cold place to a warm place?
condensation, when an object goes from a cool place to a warm place, or vice versa, the change in air temperature forms a dew like liquid; condensation
Do you treat bruised ribs with cold or heat?
Warm
What Moves cold air out and warm air in?
warm air rises cold air goes down sinks
How does warm fronts developed?
warm air goes over cold air.
Is plutonium cold or warm?
Plutonium is warm; the cause is the heat released by radioactive decay.
What is the transfer of heat energy?
thermal energy. The transfer of heat happens when a warm fast moving molecule run into slow a cold ones the heat is then transferred from the warm molecule to the cold oneAnswerHeat is energy in transit from a higher temperature to a lower temperature. Heat isn't transferred; heat describes the process of transfer.
