In physical change, matter stays the same and its chemical structure is unaffected. However, it's physical look is changed.No new compound is formed in a physical change.
they measure with a devise
physical :D I hope that helps
Not always. The weather and the temperature have a lot to do with it. If it stays warm they change later, if it gets cold sooner they change sooner.
if you were smart u would know that u just have to write TINECIBE. it meens there is no enargy change in it. it stays the same.
The earth's axis is tilted. When it goes around the sun, the equator stays the same distance from the sun, so the temperature doesn't change much.
physical change
Matter can not change. Its weight always stays the same NO MATTER WHAT, and it can be moved
Your mass stays the same no matter where you are. Your weight will change.
The compsitions stays the same :0
the matter always stays the same, expansion and contraction just means the matter is becoming more/less spread out from one another. A change in the state of matter is turning from solid-liquid-gas. The amount of matter always stays the same!
Temperature remains constant
The amount of mass stays the same.
it changes forms and the matter stays the same because of adam tonon
No, it just changes phase from a Solid to a Liquid. It's chemical makeup and "kind of matter" stays the same.
The change is physical because the change is reversible. Evaporate the water and you are left with the sugar, no new substances are produced; the sugar stays sugar and the water, water.
A controlled variable means that it stays the same while other substances change. This helps prove the exact changes in an experiment.
Yes, it decreases very slightly. We cannot measure the change directly. :)
