thermal energy is added to four identicals 1.0kg samples of water at room temperature which of the following increases in each sample

Question: Thermal energy is added to four identical 1.0 kg samples of water at room temperature. Which of the following increases in each sample?

a. average charge of an electron

b. average density of a nucleus

c. average mass of a proton

d. average speed of a molecule

Answer:

"The average speed of a molecule" increases in each of the sample when thermal energy is added to four identical 1.0 kg samples of water at room temperature.

Explanation:

When thermal energy is added to the molecules and the atoms present start vibrating in faster mode. When the vibration is faster and the space decreases between the atoms. The vibration and speed are inversely proportional. The motion as well as the spacing states the the state of the matter of the substance. The final result will expand and give more space. When they have more energy i. e. thermal energy the particles can move faster.
