the sun
heat is a form of energy and hot means giving off heat
stars which the Sun is an example.
because the heat is giving off pressure so it causes it to melt :)
i dont think it would be dangerous and it wont give off heat
Combustion.
This is because of the latent heat of freezing that it first has to give off in order to turn into ice. Latent heat means 'hidden heat'.
One non-example of heat is a block of ice in a freezer. The ice is cold, not giving off heat energy, but rather absorbing heat from its surroundings to melt and become warmer.
twinkle? They just sit there, burning, giving off light and heat energy...they also look pretty :D
It is a chemical change because the chemical composition is changed during this reaction.
An exothermic reaction releases heat energy by giving off heat to the surroundings. This happens when the bonds in the reactant molecules are broken and new bonds are formed in the product molecules, releasing energy in the form of heat.
heat it to 1665 degrees Fahrenheit and it'll boil - and also ignite giving off nasty fumes that will make you sick
The proper name for combustion is a chemical reaction in which a substance reacts rapidly with oxygen, giving off heat and light.
