Complete the sentence: during an inelastic collision, the total momentum of the system is

, while kinetic energy is .

Explanation:

A collision in which some part of a kinetic energy is changed into another form of energy is known as an inelastic collision.

In an inelastic collision momentum is conserved because total momentum of both the objects before and after the collision are same.

Whereas kinetic energy during this collision is not conserved because a part of kinetic energy changes into heat, sound and deformation of objects.

Thus, we can conclude that during an inelastic collision, the total momentum of the system is conserved, while kinetic energy is not conserved.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
