Physical change is a change in color texture and ect chemical is the change in the actual substance
Answer:
I. dissolving more solute in an unsaturated solution
Explanation:
A saturated solution is the solution which contains maximum concentration of solute dissolved in solvent.
However, if the solution is being provided with energy (heating) , it will dissolve more heat and the solution that cannot even dissolve more solute after heating is super saturated solution.
<u>Both saturated and supersaturated solutions have maximum of their capacity to dissolve the solute and hence further energy requires energy and these processes are non-spontaneous.</u>
<u>An unsaturated solution can dissolve more solute easily and thus is a spontaneous process.</u>

1.429 atm - 1086mmhg
9361 pa-9.36 KPa - 70.21 mmhg
725 mmhg -0.95 atm- 96.26 kpa
calculation
(a) 1 atm = 760 mmhg
1.429 atm = ?
1.429 x760/1 = 1086.34 mm hg
(B) 1 mmhg = 101.325 kpa
? =9361 KPa
9361 x1 /101.25 =70.21 mmhg
760 mm hg= 101.325 KPa
70.21 mm hg=?
70.21 x101.325/760 = 9.36 Kpa
(C ) 1 atm = 760 mmhg
? = 725
= 725 x1/ 760=0.95 atm
1 atm = 101.325 kpa
0.95 =?
0.95 x101.325/1 = 96.26 KPa
V₁ = <span>178 mL - initial volume
</span>T₁ = 0 ⁰C = 273K - initial temperature
V₂ = <span>211 mL - final volume
</span>T₂ =? - final temperature
According to Charles's law when pressure is constant the Kelvin temperature and the volume will be directly related:
V₁/T₁=V₂/T₂
178/273=211/T₂
0.65=211/T₂
T₂=324K= 51⁰C
