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

Question

Quizplus · Accepted Answer

When thermal energy is added to water, the kinetic energy of its molecules increases, which translates to an increase in the average speed of the molecules. The properties of subatomic particles (charge of an electron, density of a nucleus, mass of a proton) do not change with temperature.
