Answer:
<h2>A. Nearsightedness</h2>
Explanation:
A nearsightedness is an eye defect that occurs when someone is only able to see close ranged object but not far distance object. According to the question, if the length of my eye decreases slightly as I age, this means there is a possibility that I will find it difficult to view a far distance object as I age.
At 70, once my eyes had decreased slightly in length, this means I will only be able to see close ranged object but not far distant object, showing that I am now suffering from nearsightedness according to its definition above.
Answer:
The answer is: all of the answers are correct.
Explanation:
Entropy is defined as the magnitude of the irreversibilities of a process. Entropy is the disorder of molecules within a system. If the system is closed, entropy is produced if the process is irreversible. If the system is subjected to expansions or energy transfer, the entropy increases.
A process is reversible if the system and its surroundings are returned to their initial states. In a quasi-static process it is characterized by being a reversible process in which there are no irreversibilities. The entropy in this system is constant in the system.
Answer:
It is a example of physical change
Answer:
vol = 46,566 cm³
Explanation:
calcular el volumen de un cubo 36 cm
find: volume
let side of a cube = 36 cm
vol = side ³
vol = 36 ³
vol = 46,566 cm³
Answer:
ΔS = 7.618 J/K
Explanation:
The entropy change associated to an isothermal process is:
ΔS = 
We can calculate Q (heat) how:
Q = nRTln(
)
Where Vf = 2.5v
Vi = v
R = 8.314J/mol.k (Constant of ideal gases)
n: Number of moles = 1 mol
Then
Q = nRTln(2.5)
ΔS = 
ΔS = (1)(8.314)ln(2.5)
ΔS = 7.618 J/K
