Answer:
If the cell is placed in a surrounding solution which is hypotonic in nature.
Then the water from outside of the cell to the inside of the cell. The water will keep on moving from the outside of the cell to the inside of the cell.
The flow of water will take place until the outside environment of the cell and the inside of the cell becomes equal.
The flow of water will take place from the outside of the cell to the inside of the cell.

I think it's the last one
Explanation:

To solve this problem it is necessary to use the calorimetry principle. From the statement it asks about the remaining ice, that is, to the point where the final temperature is 0 ° C.
We will calculate the melted ice and in the end we will subtract the total initial mass to find out how much mass was left.
The amount of heat transferred is defined by
Where,
m = mass
c = Specific heat
Change in temperature
There are two states, the first is that of heat absorbed by that mass 'm' of melted ice and the second is that of heat absorbed by heat from -35 ° C until 0 ° C is reached.
Performing energy balance then we will have to
Where,
= Heat absorbed by whole ice
= Heat absorbed by mass
= Heat energy by latent heat fusion/melting
Replacing with our values we have that
Rearrange and find m,
Therefore the Ice left would be
Therefore there is 0.079kg ice in the containter when it reaches equilibrium
Answer:
E = h f = h c / λ energy of single photon
n E = 4.00E-11 W/m^2 energy required for visibility
n h c / λ = 4.00E-11 number of photons required for visibility (per square meter)
n = 4.00E-11 * 5.00E-7 / (6.63E-34 * 3.00E8)
n = 20.0E-18 / 19.9 E-26 = 1.00E8
100 million photons would be required on 1 m^2 to create visibility
a / A = π * (3.6E-3)^2 / 1 = 4.07E-5 fraction of area available
4.07E-5 * 1.00E8 = 4.07E3 photons required
