Albert Einstein is quoted as saying, “Not only to know how nature is and how her transactions are carried through, but also to reach as far as possible the utopian and seemingly arrogant aim of knowing why nature is thus and not otherwise.” What do you think Einstein meant by this?
Disung dishing chemical and physical change
There ar sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample.
You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change.
Each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. Also, you should assume that you can see the
entire sample, and that the sample is in a sealed box, so that no matter can enter or leave.
Sample of Substance X
Change 1
Change 1 is:
impossible
O a physical change
O a chemical change
Change 2
Change 2 is:
O impossible
O a physical change.
O a chemical change.
Change 3
Change 3 is:
O impossible
O a physical change
O a chemical change
What is wrong with this statement?
"The results of the experiment do not agree with the theory. Something must be wrong with the experiment."
