Alcohols have higher boiling points than do ethers and alkanes of similar molar masses.
<h3>What is meant by Boiling Point ?</h3>
The temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid is called the boiling point of the substance.
Approximately boiling point of Ethanol: 78.4°C, ether: 34.6°C, ethanes: 68°C
The reason for the difference is that it takes more energy to separate alcohol molecules then it does to separate alkane molecules and ether molecules.
The OH group in alcohol allows molecules to engage in hydrogen bonding.
Therefore Boiling point are in the order ;
Alcohol > alkane > ethers

Answer:c
Explanation:
A valley will be carved out due to erosion.
The volume could be calculated by using <span>V = n RT / P </span>
In which V = Volume
n = number of Moles
R= The Gas constant
T = Temperature (ideally this would be in Kelvin, but i don't see it in the option)
P = Pressure
I believe the answer is
<span>V = (1.5mol) (0.08205 L*kPa/K*mol) (22Celsius)/100 kPa

Answer: The look of the Earth has changed over time but continents have always been part of the picture. They didn't always look the way they do today, but yes, there have always been continents on Earth. Earth's continents are constantly in motion, and by running the tape ... against southern Europe, while the Atlantic will be a far wider ocean than it is today. ... During the war, Hess had used sonar to map some areas of the ocean floor in detail. ... away from both sides of the mid-ocean ridge at the same rate.
