The initial temperature of the fluorocarbon gas is 
The final temperature of the fluorocarbon gas is 
The initial pressure is 
The final pressure is 
Generally the equation for adiabatically reversible expansion is mathematically represented as
![T_2 = T_1 * [ \frac{V_1}{V_2} ]^{\frac{R}{C_v} }](https://tex.z-dn.net/?f=T_2%20%3D%20%20T_1%20%20%2A%20%5B%20%5Cfrac%7BV_1%7D%7BV_2%7D%20%5D%5E%7B%5Cfrac%7BR%7D%7BC_v%7D%20%7D)
Here R is the ideal gas constant with the value

So
=> 
Generally adiabatic reversible expansion can also be mathematically expressed as

=>
=> 
=>
So

=> 
La química está interviniendo en la industria textil, investigando las maneras de dar mayor resistencia y ligereza a la pieza, hacerla más duradera, más suave, más confortable, más funcional y práctica, tejidos capaces de mutar de manera instantánea en función de la climatología o la reacción al esfuerzo del propio

there aint rlly an explanation tbh
I metals can only share electrons. Therefore they cannot bond together

Molarity is used to measure the concentration of a solution , so it is also as molar concentration. It is denoted as M or Mol/L
<u>We </u><u>are </u><u>given </u><u>that </u><u>:</u>
- Weight of
= 5.34g - Volume of solution = 214 ml , or 0.214 L
The molar mass of magnesium chloride (
) is 95.21 g / mol
We can calculate the molarity of the solution by dividing the number of moles of solute by volume of solvent in liter ,i.e:
ㅤㅤㅤ⸻( 1 )
<em>Where,</em><em> </em>
- M = molarity
- n = number of moles
- V = Volume
We can calculate the number of moles by dividing the actual mass by its molar mass ,i.e:
ㅤㅤㅤ⸻ ( 2 )
<em>W</em><em>here,</em>
- n = number of moles
- m = molar mass
- w = actual mass
<u>Therefore</u><u>,</u>
