an uncovered pot of water lies out in the sun. which statements correctly describe what happens at the surface of the liquid water? (more than one answer)

1) the vapor pressure remains constant regardless of the water temperature.

2)the vapor pressure is produced by water molecules that have evaporated.

3) the vapor pressure increases as the sun heats the water in the pot.

4) evaporation stops once the vapor pressure reaches a certain point.

5) evaporation and condensation both occur on the liquid’s surface.

Explanation:

At a given temperature, the pressure exerted by the vapors on its condensed phases in a closed system is known as vapor pressure.

Therefore, when an uncovered pot of water lies out in the sun then heat caused due to radiation of sun will heat the water. As a result, vapors start to form after a certain interval.

So, when heat inside the system increases then there will be increase in vapor pressure of the system.

Thus, we can conclude that the following statements correctly describe what happens at the surface of the liquid water:

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

let that person have a turn to speak : )
