2.37eV stopping potential would be required to arrest the current of photoelectrons.
<h3 /><h3>What is stopping potential ?</h3>
The minimal negative voltage that must be provided to the anode to halt the photocurrent is known as stopping potential. When expressed in electron volts, the maximal kinetic energy of the electrons is equal to the stopping voltage.
Kmax = eV₀
2.37eV = eV₀
V₀ = 2.37eV

By the isotherm process, the gas will dissolve in 4.5 atm.
It is important to know about isotherm conditions to solve this problem. The isotherm process is a cycle that has the same temperature but different pressure and volume. The process should follow the rule
P1 . V1 =P2 . V2
where P1 is initial pressure, V1 is initial volume, P2 is final pressure and V2 is the final volume.
From the question above, the parameter given are:
P1 = 2 atm
V1 = 1 L
P2 = 4.5 atm
By substituting the parameters to the rule, we get
P1 . V1 =P2 . V2
2 . 1 = 4.5 . V2
V2 = 2 / 4.5
V2 = 0.44 L
Hence, the gas will dissolve in 4.5 atm.

They got back in the Lunar Explorer Module
Hints:
The Earth's energy does not come from eating a balanced diet,
or from ninja turtles, or from getting sleep and exercise.
There are no hamsters running on a treadmill inside the Earth.
God didn't wind up a big spring to operate the Earth.
The Sun provides, and has always provided, almost all of the energy
used on Earth. It was the energy that got stored in dead dinosaurs
to make gas and oil, and it's the energy that makes plants grow, and
gets stored in them so we can get the energy by eating the plants.
Answer:
The volume can be calculated once the mass is determined.
Explanation:
Gas is a fluid that can be compressed, therefore knowing the volume of the container is not sufficient reason, to determine the volume. That is why it is important to always know the mass of the gas since the mass can not be destroyed will always be conserved the same. So if we have a gas in a container, and if we know its temperature and pressure, we can determine its specific volume, once this property is determined, we can calculate the volume by knowing the relationship between the specific volume and the mass of the gas.
