HW Questions

Matter is anything that has mass and takes up space. There are different aspects of matter including boiling and melting temperatures.

Matter can be divided into mixtures and substances. Mixtures contain at least two kinds of matter and there is either a homogeneous mixture or heterogeneous mixture. Homogeneous means that all the samples are the same throughout and heterogeneous means that not all samples are the same. Also, substances include elements and compounds. Elements contain only one type of atom and compounds contain more than one type of atom.


3.    A method I could use to separate a mixture is paper chromatography. I could separate water-soluble ink into its components. Also, you could separate mixtures by sorting, filtering, heating, or cooling.
