Question

Three light sticks are activated at the same time. One stick is placed in a beaker of hot water, one in a beaker of ice water, and one remains at room temperature. Which is the likely result? A) The hot stick is brightest, and the cold stick is dimmest. B) The sticks in water are brighter than the one in the room air. C) The hot stick is dimmest, and the cold stick is brightest.

Answer 1

%%%%%%%%%%%%%%%%%%%%%%%% A.

Answer 2

Answer: Option (A) is the correct answer.

Explanation:

It is known that rate of a reaction depends upon temperature. This means that more is the temperature more will be the kinetic energy of particles.

Hence, this will cause greater number of collisions between the particles. As a result, rate of reaction will become faster.

Thus, we can conclude that the result for the given situation will be that the hot stick is brightest, and the cold stick is dimmest.
