Answer:
1-<u>Pentanol </u>has the highest boiling point.
Explanation:
Boiling points of given compounds are as follow,
1) 2-Pentanone = 101 °C
2) 1-Pentanol = 138 °C
3) Pentane = 36.1 °C
4) Pentanal = 103 °C
Pentanol has greatest boiling point as compare to others because it involes a strongest intermolecular interactions called as hydrogen bond interactions. Remaining compounds lack the direct attachement of hydrogen to most electrnegative atom like oxygen which is present in 1-Pentanol.
3.75 litres is the volume of the balloon indoors at a temperature of 25°C.
Explanation:
Data given:
initial temperature of the gas in balloon = -35°C or 238.15 K
initial volume = 3 litres
final temperature = 25 °C or 298.15 K
final volume =?
pressure remains constant
From the data given when pressure is constant Charles' law is applied.
= 
Rearranging the equation to know the final volume of the gas in balloon
V2 = 
V2 = 
V2 = 3.75 Litres
when the temperature of a gas is increased and pressure remains constant the volume of the gas increases.
