Arturiano [62]

The second volume : 42.2 L

<h3>Further explanation</h3>

Given

51.7 L at 27 C and 90.9 KPa

Required

The second volume

Solution

STP = P₂=1 atm, T₂=273 K

T₁ = 27 + 273 = 300 K

P₁ = 90.9 kPa = 0,897 atm

Use combine gas law :

P₁V₁/T₁ = P₂V₂/T₂

Input the value :

0.897 x 51.7/300 = 1 x V₂/273

V₂= 42.20 L

An experiment is performed using 7 liquids; Methanol, Ethanol, Propanol, Butanol, Water, Pentane and Acetone.
charle [14.2K]
A). The weaker the IMF the lower the evaporation rates of each liquid. So Pentane had the weakest IMF and Butanol has the strongest.

b).They all evaporate at different rates because of their differences in their bonds. Not all liquids are the same and they will all most likely evaporate at different times
