Heterogeneous means of different types. So a heterogeneous mixture is a mixture of dissimilar items. Homogeneous means of the same type so a homogeneous mixture would be a mixture of similar items.
A mixture where two or more substances are mixed together but are not chemically combined is called as an heterogeneous mixture.
In chemistry, heterogeneous mixture is a mixture of two or more different substances in the form of solution or colloids. For example, salad is an heterogeneous mixture
A heterogenous mixture is not uniform in composition and properties throughout.

Like all molecules, a molecule of H20 is in constant motion;
'hot' molecules move faster than 'cold' molecules. If the molecules
move slowly enough the substance appears stationary to us (frozen
water) and if they move quickly enough they will expand to fill
their container (vapor or gas water.)
