Final answer:

Boiling a pot of tap water requires an increase in energy and the water is undergoing evaporation.

Step-by-step explanation:

The statements that are true about the process of boiling a pot of tap water are:

  1. The water's change of state requires an increase in energy. Boiling is an endothermic process where heat energy is added to convert the liquid water into water vapor.
  2. The water is undergoing evaporation. Evaporation is a process where the surface molecules of a liquid gain enough energy to escape into the gas phase.

Final answer:

OPTION A AND C.

True statements about boiling tap water are that it requires an increase in energy, and it involves a loss of energy to the surroundings. Boiling is an endothermic process and is distinct from sublimation and evaporation.

Step-by-step explanation:

When considering which statements are true about the process of boiling a pot of tap water, the correct statements are:

  • The water's change of state requires an increase in energy (a).
  • The water's change of state involves a loss of energy to the surroundings (c).

Boiling is an endothermic process where heat is added to the water, causing an increase in the energy level of water molecules. This increase in energy leads to a higher level of disorder as the molecules overcome the attractive forces holding them together and transition from the liquid phase to the gas phase. Sublimation is not occurring, as this process refers to a solid turning directly into a gas, which is not the case when boiling water. Also, evaporation happens at any temperature when molecules at the surface of the liquid gain enough energy to enter the gas phase, while boiling occurs throughout the entire volume of the liquid at its boiling point.
