C: Hydrogen bonds tighten
Explanation: As temperature increases in water, the kinetic energy of the water molecules also increases. This increased kinetic energy leads to more frequent collisions among the water molecules, which causes the hydrogen bonds between them to break and reform more frequently. When the temperature is high, the hydrogen bonds tighten less frequently, and more water molecules gain enough energy to break free from the liquid and become vapor, leading to increased evaporation.
As temperature increases in water, there is increased evaporation. Which of the following BEST explains why this happens?
A: Covalent bonds form
B: Surface tension decreases
C: Hydrogen bonds tighten
D: Heat capacity lowers
