Does heat flow from warm to cooler substances?
Yes. Heat flows from a warmer to a cooler substance. The technical term is: The Second Law of Thermodynamics.
What happens when thermal energy is transferred from a warmer object to a cooler object?
When thermal energy is transferred from a warmer object to a cooler object, heat flows from the warmer object to the cooler object until they reach thermal equilibrium. This transfer of heat causes the warmer object to cool down and the cooler object to warm up until their temperatures become the same.
Is heat always transferred from a warmer substance to a cooler substance?
Yes. (That's why refrigerators are a kind of a trick - an inefficient one.)
Thermal energy is transferred in gases or liquids primarily by?
Thermal energy is primarily transferred in gases or liquids through the process of convection. In convection, heated molecules become less dense and rise, while cooler molecules sink, creating a circular motion that transfers heat energy throughout the substance.
What happens to the temperatures of a hot and cold substance when they come into contact with each other?
When a hot and cold substance come into contact with each other, heat will transfer from the hotter substance to the cooler one. This transfer of heat will cause the temperature of the hotter substance to decrease and the temperature of the cooler substance to increase until they reach thermal equilibrium.
Is it true that thermal energy always flows from a cooler substance to a warmer substance?
No. The opposite would be true.
A warmer substance has more of what than a cooler one?
A warmer substance has more thermal energy than a cooler one, which is a measure of the internal energy present in a system. The higher temperature of the substance indicates that its molecules are moving faster, leading to a greater amount of thermal energy.
What does hygroscopic mean?
It means any substance that readily absorbs moisture, like from the atmosphere. i.e wool goes by this term therefore has thermal qualities when laid as a carpet, in winter it absorbs the moist cold air leaving the atmospere in the room warmer and in summer it actually absorbs up to 30% of the humidity thus leaving it cooler.
Does heat flow from warm to cooler substances?
Yes. Heat flows from a warmer to a cooler substance. The technical term is: The Second Law of Thermodynamics.

How heat move'?
Thermal energy that can move from one substance to another is called heat. Heat always moves from a warmer substance to a cooler one. An increase in temperature means that heat moves into a substance.
Thermal energy is transferred in gases or liquids primarily by?
Thermal energy is primarily transferred in gases or liquids through the process of convection. In convection, heated molecules become less dense and rise, while cooler molecules sink, creating a circular motion that transfers heat energy throughout the substance.
What happens to the temperatures of a hot and cold substance when they come into contact with each other?
When a hot and cold substance come into contact with each other, heat will transfer from the hotter substance to the cooler one. This transfer of heat will cause the temperature of the hotter substance to decrease and the temperature of the cooler substance to increase until they reach thermal equilibrium.
What does decrease mean in temperature?
Decrease in temperature means that the temperature is getting lower or becoming cooler. It indicates a reduction in the amount of thermal energy present in a system or substance.
When a warm object is placed near or in contact with a cooler object which type of energy will be transferred?
Thermal energy is the sum of all kinetic and potential energy in a substance. Heat is the thermal energy that flows from a warmer object to a cooler object. Heat flows only one way, from warmer to cooler objects. Net heat transfer ends when two objects reach the same temperature.........if this Help?
Why does a black asphalt road become hotter than white cement sidewalk in the same amount of sunlight?
The darker the color of the road the more sunlight it absorbs. A white cement sidewalk is whiter which absorbs many of the colors making it cooler.
