Because of the heat, steam
Answer:
True
Explanation:
GIBBS FREE ENERGY (G) Gibbs free energy is a thermodynamic function It is a state function. G = H - TS At constant temperature At constant pressure and temperature An increase in S corresponds to a decrease in free energy
Constant free energy (G) P, T The important thing about free energy is that whenever the pressure and temperature are constant, we can determine the spontaneity of a process only in terms of the thermodynamic properties of the system G = H - TS The Free energy change is a measure of the change in the total entropy of a system and its environment at constant temperature and pressure. <u>Spontaneous processes at constant temperature and pressure are accompanied by a decrease in free energy</u>.
At constant temperature and pressure, the direction of spontaneous change is towards the lowest free energy. <u>The equilibrium state of a system corresponds to the lowest point of the free energy curve
</u>.
Answer:
Sodium and Chlorine would be the answer for this :)
<u>We are given:</u>
half-life of carbon = 5715 years
Initial mass = 100 grams
Final mass = 12.5 grams
<u>Finding the time taken:</u>
<u>Number of half-lives:</u>
We know that in the relation:
, n is the number of half-lives taken
replacing the given values:
12.5 / 100 = 1/2ⁿ
1/8 = 1/2ⁿ
2ⁿ = 8
2ⁿ = 2³
n = 3
Hence, it took 3 half-lives to reduce the mass to 12.5 grams
<u>Number of years:</u>
Time taken = 3 half-lives
we know that one half-life is 5715 years, replacing that value:
Time taken = 3*(5715) years
Time taken = 17145 years
Therefore, after 17145 years, a 100 gram sample of carbon will decay and only 12.5 grams will remain
The question ask on which of the following is the best representation of adhesion, cohesion and surface tension of water and the answer among the choices is letter C. Water droplets forming a bead like shape over a glass table. I hope you are satisfied with my answer.
