I assume you are asking about the difference between weight and mass. Weight is usually measured by a spring and would be different on the earth and the moon. Mass is essentially measured with a balance relative to a standard and would be the same on the earth and the moon.
A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes. An example of a chemical change would be burning paper and getting ashes. A physical change can be undone. An example of a physical change would be bending the paper because you can still get the paper back and no new substance is created.
it changes the whole appearance and physically changes the substance.
its a chemical reaction . u cant get back raw onions after they r cooked! can uuuuuuuuuuuuu ??????????
Try to break it down by physical and chemical means until you cant really break it down anymore, that's your best chance of identifying it as a pure substance. To help you identify it, there are each elements physical properties,(color,shape,texture,states at different temperatures, and other things that can be observed without change to the substance.) which are better to use for observance than Chemical Properties, because they usually cant be reversed and cause change to the material.
Something burning is a chemical change because it is combining with the oxygen in the air. Ex. when you burn sugar you get c02 and water, the reason the water doesnt put out the fire is that the water is released as a gas.
the answer is mass
chemical .... :0)
you cant but you can change score limit to 30,000
A physical property is something like color, size, and state. The substance still stays the same! A chemical property is a change in substance. Burning is a chemical property because if you burn a piece of wood, it is a new substance and you cant change it back to regular wood. It is usually very hard to change a chemical change BACK to its original substance. The answer to this is No
