How would you describe the changes that happened to the material when cooled?
Changes in physical properties: cooling is temperature decrease caused by heat exchange
What changes electrical energy into heat?
when electrons flow through a conductor then the material of the conductor offers resistance to excite the electrons in the conductor to release heat energy.
Would material absorb more heat?
If there was more heat to absorb than was already in the material.
Can you explain the transfer of heat within a material?
The transfer of heat within a material, I don't know about. But I can help you with the transfer of heat from one material to another. Heat always moves from the warmer material to the colder one. It does this until it reaches equilibrium. this means when both objects have the same amount of heat energy.
Does the flame destroy the candle or just change its form?
The flame changes the form of the wax and the material of the wick into heat, light, and the carbon, and gases given off as smoke.
How do changes in heat energy affect the density of earths mantle material?
How do changes in heat energy affect the density of earths mantle material
What is thermochimic film?
it's a piece of material that changes colour when applied to heat... so this isn't really a filmmaking question...

What does a smart material cause?
a smart material causes very few affects but they are great to use to re shape something like a spring when it is hit by the heat it can be remoulded and then heat hits it again and it can return to its original shape...I think? But anyway I am not sure how long it takes for a spring to be returned to its original shape and expectations.
Explain your understanding of how heat transfer from one material to another?
because thats how the water or weather changes
Effects of heat on fats and oils?
effect of heat on fire On heating the fatty acids and glycerol is produced.Heamoglobin in meat decomposes and changes the red colour in brown.
Do mood rings really work according to mood?
No, it changes according to heat. For example if you hold in tightly in your hands, it will change colour.
What does thermochromic mean?
advantages include a dynamically variable performance and not having to change products using thermochromics for different circumstances like prescription glasses. disadvantages include not always changing completely and being too opaque. hope this helped. x :)
What is mood ring and how does it work?
A mood ring is a ring that if we wear it the colour of the ring changes.Each colour means a different mood. but it does not actually work.It changes its colour with the hepl of the temperature.Try putting the mood ring in the referigerator for a while and see.Dont ever put the ring in water
What are the 3 main types of heat transfer and how are each of the different?
Radiation - electromagnetic, thus no material need be in contact with the radiating object. Conduction : heat conducted by direct contact. Convection : heat is 'conducted' to a transfer material (fluid) which then caries it away by gravity (changes in density).
How does heat change a material and can it change back?
Heat raises the temperature of the material. If the change is small then there is only a physical change and allowing the material to return to its original temperature will return it to its original physical state.However, too much heat can result in chemical changes which are usually not reversible. For example, if you heat a piece of plastic enough it will crumple into a charred mass. That charred mass will not return to the pristine plastic.
What is an indicator of a chemical reaction?
HEAT, Heat is the the number one indication of a reaction. Also, changes of state of matter and mass are also indicators of a chemical reaction. an example is when an iron fence rusts.
