Explain please? :[Is the following sentence true or false? All samples of a substance have different physical properties?
False.
If you take ten samples from a lake, are they all still water?
Their CHEMICAL properties MIGHT differ but, physically, they should be the same.Is the following sentence true or false? All samples of a substance have different physical properties?
Uhh, i think your missing a part of the question or not giving information that is needed. It depends because even though a molecule have the same compounds doesn't mean they are geometerically shaped the same and that is why we have different amino acids with the same chemical formula.
false you can only take the same sample from the same substance
plural (substances) however it can be true.
True. Water: same substance, but can be a sample of vapor or ice or liquid, which all have different physical properties.
