For example pure silicon doesn't expand in a given range of temperature.
Also a mixture of amorphous and crystalline quartz has a thermal expansion coefficient near zero ("Zerodur" from Schott).
But the majority of materials suffer thermal expansion.
Within a certain limited temperature range, water does not expand on heating, but on cooling. That's why ice floats,
Between 0 and 4°C, water will contract when heated.
They expand ------- No, normally metals expand when heated.
no, cuz there is a thing called the expansivity of a substance that tells us how much a particular substance will expand over 1 degree change in temprature
compound as it decomposed into two separate things.
Liquids expand more than solids on heating
Its very unusual for a substance to expand when it freezes, water is just odd that way. Its just a property of water, its moleucles expand in the area they take up and take up more space.
All objects do not expand on heating.....Only metals expand on heating.....non metals like wood,plastic,etc do not expand on heating.
All liquids expand on heating (apart from water between 0oC to 4oC)
An increase in temperature of the substance causes it to expand.
Heating a substance usually makes it expand Heating a substance can make it change state (solid to liquid, liquid to gas, gas to plasma) Heating a substance can make it emit light at shorter wavelengths Heating a substance can make it more malleable.
Yes, it does
i am a solid substance left after heating coal or petol
It depends on the solid.
Heating a substance can result in a chemical reaction, which usually results in a simple combustion reaction. This is because Oxygen, or O2, is added to the substance, which can dramatically alter the substance.
