Chloroform can help preserve a water sample by inhibiting the growth of bacteria and microbes that could degrade the sample. It acts as a disinfectant by disrupting the cell membranes of microorganisms, preventing them from multiplying and breaking down the organic matter in the sample. This preservation method allows for more accurate testing and analysis of the water sample over an extended period of time.
Mass is an extensive property, which depends only on the amount of matter in the sample, not on the composition of the sample.
No.

A sample of water molecules is an example of a matter where all the particles (H2O molecules) are identical. Each water molecule consists of two hydrogen atoms and one oxygen atom, making them indistinguishable from one another.
Yes, leaves are a sample of matter. Matter is anything that has mass and takes up space. Leaves are composed of atoms and molecules, making them a form of matter.
No. Boiling point is an intensive physical property, which means it does not matter how large the sample is.
