What occurs when energy is added or taken away?
When energy is added,solid will melt into liquid or liquid will change into gas. (When energy is added it gains heat).When energy is removed, the liquid will turn into solid or the gas will turn into liquid. (When energy is removed the heat will lose).
When leaves fall from the trees is it a physical or chemical change?
chemical change.change, added on to by upupin-I believe it changed color because of the chlorophyll that dies off because the length of sunlight hours decreases during winter time
What is added to change a solid to a liquid?
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
How do you classify the difference between a physical and chemical change?
Physical changes occur when objects or substances undergo a change that does not change their chemical composition. A physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.
What type of change occurs when water is added to a salt-sulphur mixture?
The salt dissolves in the water and the sand does not.
Is melting of butter physical change or chemical?
Physical, because the stuff that the butter is made out of doesn't change, just the state, or physical form, that it is in. (solid to liquid.)
Is melting chocolate a chemical or physical reaction?
It is a physical state change from a solid to a liquid. It is not a chemical change, unless other ingredients are then added when melted - as usually happens when used in cooking, for instance.

Is glass melting a chemical change?
I believe melting most items is a physical change as you are only changing the state of the matter, not it's composition. There may however be a breakdown that occurs depending on the composition of the glass with high enough temperatures. This would change the chemical composition. I believe you can relate it to melting plastic (don't actually do this as it releases toxic gases). At low enough temperatures it just becomes soft and moldable. At higher temperatures you burn it down and cause changes in the material. I'm no expert
