You don't have to go far to find such a mixture . . . you're breathing it !

Earth's atmosphere is a mixture of nitrogen, oxygen, argon, and
several other gases.  Except for carbon-dioxide and water vapor,
the others are all elements, not compounds.

<span>Yes, a mixture could be made up of only elements and no compounds, given that the elements never undergo a chemical interaction and stay only in physical contact with each other.</span>

Answer:

Potential

Explanation:

The water in the bathtub has more potential energy than that in the tea cup because it has a greater number of water molecules.

Mass is a parameter that is very instrumental in determining potential energy.

The potential energy of a body is the energy due to the position of that body.

   Potential energy  = mass x acceleration due gravity x height

Mass is the amount of matter in a substance. Water in the tub will have more mass and contain a greater number of water molecules there in.

Since potential energy is directly proportional to mass, then, it will have a greater amount of potential energy.
