The answer is B - vegetable oil.
Explanation:
The properties of liquids depend on the attractions the molecules of the liquid have for each other and for other substances.
Liquids can dissolve certain other liquids, depending on the attractions between the molecules of both liquids.
Polar liquids, like water, dissolve other liquids which are polar or somewhat polar.
Polar liquids, like water, do not dissolve non-polar liquids like oil.
Answer:
D
Explanation:
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
<h2>The required "option is b) potential energy".</h2>
Explanation:
- The energy which is associated with the motion of the object is called kinetic energy.
- The energy which is associated with the amount of heat released is known as thermal energy.
- The energy which is released during a chemical reaction is known as chemical energy.
Therefore, option (a), (c), and (d) are incorrect.
- The energy which is possessed by a stationary object or associated with the position of an object is called as potential energy.
- Hence, the correct option is potential energy.
