Darwin observed how farmers and breeders produced many kinds of farm animals and plants. These plants and animals had traits tha

t were desired by the farmers and breeders. He also noticed how the study of similar body structures and vestigial organs could add to the evidence of evolution. After performing several breeding experiments, he came to certain conclusions and formulated some theories. His theory of evolution and natural selection is the most accepted one. What is the reason behind the acceptance of Darwin's theory? A) It is supported by practical evidence and examples. B) It is supported by its harmonizing with other views. C) It is based on the ideas of earlier hypothesis and laws. D) It is based on the practical example of Lamarck’s theory

the answer is A......

it is supported by practical evidence and examples. this is the answer because he tried and tested many different ways to see what would happen so he is happy with the conclusion that what he tested is what he gets.

What happens to the average kinetic energy of the particles in a sample of matter as the temperature of the sample is increased?
antiseptic1488 [7]

Answer:

  • <em>As the temperature of a sample of matter is increased, the average kinetic energy of the particles in the sample </em><u>increase</u><em>.</em>

Explanation:

The <em>temperature</em> of a substance is the measure of the <em>average kinetic energy </em>of its partilces.

The temperature, i.e. how hot or cold is a substance, is the result of the collisions of the particles (atoms or molecules) of matter.

The kinetic theory of gases states that, if the temperature is the same, the average kinetic energy of any gas is the same, regardless the gas and other conditions.

This equation expresses it:

  • Avg KE = (3/2) (R / N) T

Where Avg KE is the average kinetic energy, R is the universal constant of gases, N is Avogadro's constnat, and T is the temperature measure in absolute scale (Kelvin).

As you see, in that equation Avg KE is propotional to T, which means that as the temperature is increased, the average kinetic energy increases.
