- Extensive properties of matter are A. depend on the energy the substance possesses. B. depend on the amount of a substance present in the sample. C. are independent of the amount of a substance that is present. D. are independent on the type of substance required. OE. depend on the way a substance behaves.arrow_forwardDoes an individual atom of helium have a melting point and why or why not? Yes, the melting point of an individual atom can be measured using advanced techniques such as atomic force microscopy. No. an individual atom is too small to see so we cannot measure the temperature at which it changes from a solid to a liquid. Yes, the melting point of helium is the same whether there is one atom or one mole of atoms. No. an individual atom cannot be considered a solid or a liquid so there is no temperature at which it can change from one to the other.arrow_forward1.

Suggest ways on how to store and handle properly the different glassware to avoid accidents in the laboratory. You can use illustrations to show your idea. 3. Why is the most of the containers of substances and those used for heating are made up of glass rather than metal? 4.
