<h2>Question:</h2>
- A solution that is able to dissolve additional solute is best described as _____.
- <u>Unsaturated</u> means the substance is poured into the solvent that can be dissolved. It is a solution (with less solute than the saturated solution) that completely dissolves, leaving with no remaining substances.
- If you were to pour olive oil into a glass of water, it will dissolve, so it is <u>unsaturated</u>.

Answer:
Explanation:
Kinetic energy is the energy due to changes in position of a body. It is always with regards to motion of a body.
Potential energy on the other hand is the energy at rest of a body.
To estimate kinetic energy, we use the formula:
K.E =
where m is the mass of the body and v is the velocity of the object.
mass is 5kg and velocity is 5ms⁻¹
K.E =
K.E = 62.5J
for the object at rest;
potential energy is calculated:
P.E = mgh
where m is the mass, g is the acceleration due to gravity and h is the height
m is 5kg, h is 2 and g is 9.8
P.E = 5 x 9.8 x 2 = 98J
The moving object has kinetic energy with the object at rest having potential energy.
