15 pts! Explain how the absorption of energy (heating) affects the speed of the particles in a substance.

See explanation

Explanation:

Temperature has been severally defined as the measure of the average kinetic energy of the molecules of a body. Heat is a form of energy that exists due to temperature difference.

Given a body whose molecules has a speed = (3RT/M)^1/2; this implies that for a given mass of the substance, the velocity of its particles depends on the temperature of the substance.

However, absorption of heat increases the temperature of the body. Therefore, when heat is absorbed, the temperature increases and the speed of the particles of a substance increases according to the relation above.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

it's c (engineer's do their work with mechanical stuff not on any living being)
