Question

List these drinks in order of kinetic energy, starting with the drink whose particles have the highest kinetic energy.

hot chocolate, water, juice, milk
hot chocolate juice, milk, water
water milk, juice, hot chocolate
water, hot chocolate, juice, milk

Answer 1

Kinetic energy and heat have a direct relationship with one another. A higher temperature means a higher kinetic energy.

With that said, the answer is B.

Answer 2

Answer: Option (b) is the correct answer.

Step-by-step explanation:

The energy obtained by an object because of their motion is known as kinetic energy.

Hence, when particles of an object is moving rapidly from one place to another then it means the molecules have high kinetic energy.

Therefore, in a hot chocolate molecules will have high kinetic energy due to increase in temperature. Whereas particles of juice has more kinetic energy than milk. On the other hand, molecules of water will have least kinetic energy as only then it is existing in liquid state otherwise it would have evaporated.

Thus, we can conclude that drinks in order of decreasing kinetic energy are as follows.

hot chocolate > juice > milk > water
