I haven't found any other website which explains to me that fog is matter; I just need this to figure out what things are matter and which are not. For example, fire is NOT matter.

    $\begingroup$ A flame is indeed made of matter, sometimes it is hot enough to be a plasma which is also matter. But a flame is a mixture of gases that are undergoing chemical reactions to emit light and heat. Fog is water vapor which is gaseous water and is thus also matter. $\endgroup$ – Triatticus Sep 20 '18 at 1:50

    $\begingroup$ @Tratticus 1) If you are going to answer the question, then make it an actual answer rather than a comment 2) You typically don't want to fully answer questions like these, as it is a homework-like question where it would be better to lead the OP to the answer. $\endgroup$ – Aaron Stevens Sep 20 '18 at 1:55

fog is matter: it consists of tiny droplets of liquid water (which is matter) mixed into the gaseous air (which is also matter).
