heat moves from warmer objects to cooler objects
a-p-e-x quiz
Heat can be transferred from one place/object to another by three methods: conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass.
Heat flows from area of higher temperature to lower temperature.
Heat is a process. There is really no such thing as cold, just the absence of heat which we experience as cold.
This is a reason why "cold" does not flow to hot, but rather heat flows to areas of lower temperature.
You can think of it as an equilibrium. Hot surfaces dissipate heat to conform to the environment it is in. If something was at a temperature of 100 degrees, and confined to an environment of 100 degrees, the process of heat transfer would not occur.
The forms of heat transfer are radiation, conduction and convection.
It's hard to determine, given that you didn't include the illustration.
Heat moves to cold - which warms the cold object up, but cools the hot object down.
Heat flows from hot objects to cold.
True
An endothermic reaction is a reaction where heat flows from the surroundings in to the system. Holding an cold pack to your skin is an endothermic reaction; heat flows from your skin (surroundings) into to the cold pack (system).
If you mix a hot liquid and a cold one, the heat from the hot liquid will flow to the cold liquid, reducing the heat of the overall liquid.

There are three way to heat up something: withThermal ConductivityHeat radiationConvection.
steam
heat transfer is when heat from one object transfers to another. Heat transformation is when you have enough heat or cold to change the state of an object (ice to water).
Heat always flows from a hotter object to a colder one. So: Heat 'transfers' from 'hot' to 'cold' (cold being a relative term and considered an absence of heat).
heat transfers to the coldest thing in the area. there for, there is no such thing as hot or cold because when something is cold all you really feel in the loss of heat from your hand to the cold object. same goes for hot. all you really feel is the large amounts of heat that hot object is giving you.
Convective heat
a heat mover is a device that transfers heat from one object to another.
Heat transfers through: Conduction=Transfers heat from one object to another ex:the hot frying pan is touched by you and you can feel the heat Convection=transfers heat in air
heat travel from a hot object first then to cold object!
Heat transfers to the colder object.
Conduction of heat means that two objects with different temperatures are touching each other. The heat of the hotter object generally transfers to the cooler object. In the hotter object, molecules are moving faster. The vibration from these molecules causes the molecules in the cooler object to vibrate faster, which translates into heat.
The direction that heat flows in is From a warmer object to a cooler object.
Fire transfers by three means conduction heat transfered through an object, convection heat transferred via air as it is formed and by radiation heat moves in waves and remember heat always flows from hot to cold surfaces.
Both conduction and convection are types of heat transfer, meaning they move heat from one object to another. The difference is how they transfer the heat. Conduction transfers heat from touching solid to touching solid, while convection transfers heat in fluids (liquid or a gas).Convection transfers heat by having the warm types of fluid rise while the cold sinks. This creates something called a convection current.
