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:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
