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 shortening melting a chemical or physical change?
Melting shortening is a physical change because the molecules in the shortening remain the same. Energy is added to the shortening to break the intermolecular forces and change it from a solid to a liquid without altering its chemical composition.
Is melting chocolate a chemical or physical reaction?
Melting chocolate is a physical reaction because it does not change the chemical composition of the chocolate. It only involves the change in state from a solid to a liquid due to the application of heat.
Is melting gold and pouring it into a molt a chemical change?
No it's not because all you are doing is melting the gold, putting in into a mold and letting it harden. It would be a chemical change if you added some other substance to it during the progress.
When energy is added or removed is a physical change or chemical change?
Physical
Is most clearly an example of a physical change apex?
A solve dissolves when added to a liquid
When energy is added or removed physical or chemical change?
Physical
Is brewing a coffee chemical or physical change?
physical. the water being added simply soaks through the coffee, so there's no chemical change.
Does physical change occur when energy is added or removed?
Physical change can occur when energy is added or removed. For example, adding heat energy can cause water to change from a solid to a liquid (melting), while removing heat energy can cause water to change from a liquid to a solid (freezing). These changes do not alter the chemical composition of the substance.
Whole milk curdles if vinger is added physical or chemical change?
chemical
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
Is melting ice cube physical change?
yes because its changing from one form to another form which is physical!!!
