Data:
Q (Amount of heat) = 832 J
m (mass) = ?
c (Specific heat) = <span>0.90 J/(g × ° C)
T (final) = 97 ºC
To (initial) = 20 ºC
</span>ΔT = T - To → ΔT = 97 - 20 → ΔT = 77 ºC
Formula:
Q = m*c*ΔT
Solving:
Q = m*c*ΔT
832 = m*0.90*77
832 = 69.3m
69.3m = 832
What does it happen in smallest scale?
<span>You have to look for "DUPRE' EQUATION" which treat about </span>
<span>"TWO-PHASE INTERFACIAL FORCEs". </span>
<span>At boundary surface between two aggregation phases, you may attribute upper energy level to molecules standing at the boundary zone. So, it has to define INTERFACIAL FORCEs WHICH ACT TO REMODEL SHAPE AND EXTENSION OF MEETING PHASEs. </span>
<span>In your case, Water's Droplet is a liquid phase surrounded by Air (e.g. gas phase) and Interfacial Forces act to dominate Boundary-Surface. </span>
<span>Mathematically, smallest possible Surface comes to SPHERICAL SHAPE. </span>
During the winter solstices, we experience the longest day and the shortest night while during the summer solstices the sun is at its highest point in the sky.
<h3>What is the Solsticest?</h3>
The Solstices is the season that occurs at the moment the earth's tilt toward or from the sun is at a maximum. There are two seasons of Solstices which include the following:
- The winter solstices: This occurs when the sun is directly over the Tropic of Capricorn causing us to have the shortest day and longest night of the year.
- The summer solstices: The sun is at its highest elevations.

The redox reaction given is,
Cu₍s₎ + 2Ag⁺₍aq₎ ---------> Cu²⁺₍aq₎ + 2Ag₍s₎
The equilibrium constant for this reaction is as follow,
Kc = [Cu²⁺][Ag]² / [Cu][Ag⁺]²
Kc = [Cu²⁺] / [Ag⁺]² ∴ {[Cu₍s₎] = 1 & [Ag₍s₎] = 1
So, Above bolded is <span>the concentration equilibrium constant expression for the given reaction.</span>
Answer:
c
Explanation:
we cannot say that either will die out, because we dont know the conditions. but we know that both sides out the mountian arent exactly the same, so we know they will evolve to adapt and grow with what they have
