Due to the Hydrogen bonds existing beween water molecules.
The electronegative oxygen causes a dipole in water molecules.
The slightly positive hydrogens of one water molecule bond to the slightly negative oxygens of other water molecules. This bond formed between many water molecules results in water having a higher boiling point than alcohol. Alcohol only has Van der vaal's forces existing between their molecules and these forces are weaker than hydrogen bonds.

Why does distilling an alcoholic drink make it more alcoholic?
You can separate alcohol and water content as alcohol boils at 78 degrees C, and water at 100. The alcohol distilled off is far purer than is in say the 40% original spirit.
Why alcohols boiling point is 100 degree celsius and water 1is lower 78 degree celsius?
Water boils at a higher temperature than alcohol(ethanol) as the inter-particular bonding is stronger. Water is held together by hydrogen bonding and although ethanol is also held together by hydrogen bonding, it is weaker due to the CH3CH2- group keeping the hydrogen bonds separated.Water boils at ~100 oC whereas alcohol boils at ~78 oC.
Differences between mercury and alcohol thermometers?
Alcohol is used to measure at low temperatures because it has a lower freezing point than Mercury. Mercury has a higher boiling point than alcohol, mercury boils at around 400 Co and alcohol boils around 80 C0.
What is the boiling point of Ethonal?
Ethanol (Ethyl Alcohol) has a melting point of -130 and boils at 78.5. Ethanal (Acetaldehyde) has mp -123.5 0C and bp 20.2 0C
Why did water dried up first than acetone and alcohol?
water has a lower vapor pressure than alcohol or acetone, so it requires more heat energy to cause it to evaporate.
How Eliminate alcohol in urine test?
heat it. Alcohol boils at a lower temperature than water
What will boil first water or alcohol?
I assume that by "boils faster" you really mean "boils at a lower temperature", and that by "alcohol" you mean "ethanol". Ethanol has a lower boiling temperature than water at standard pressure. However, a mixture of ethanol and water boils lower than either by themselves do. This is called an "azeotrope" and it happens for ethanol/water mixtures at about 95% ethanol, which is why it's essentially impossible to get ethanol to more than 190 proof by distillation alone.
Why is temperature of boiling water cannot be measured using an alcohol thermometer?
Because the alcohol boils at a lower temperature than water.
Why does alcohol evaporate after than water?
Alcohol is evaporated first.

How is beer different to whiskey?
Beer is run by direct fermentation and will not exceed a maimum of 14%. The must developes alcohol which then kills the yeast endind fermentation. If the must is then boiled at controlled temperature, the alcohol which boils at a lower temperature than water than water boils out at about 180 proof, then continued boiling allows the temperature to rise to 212 degress and start putting out water and thinning the whiskey to any desired lowe amount for drinking.
Does water condensate?
No. The reason for this deals with the nature of condensation and solutions. A solution is a liquid where the dominant liquid or solvent has other solids, liquids, or ions, in it called solutes. Saltwater is a solution where water is the solvent and the salts are the solutes. When a solution boils, the solutes and solvents split apart. For example, vodka is a solution where water is a solvent and alcohol is the solute. Since alcohol boils at a lower temperature than water the alcohol boils off before the water does. In the case of saltwater, the water boils long before salt. Condensation is when a gas turns into a liquid. Since the water vapor does not carry salt (i.e. fresh water vapor from boiled saltwater), it does not condense as saltwater but as fresh water.

If water boils at 100degrees and alcohol boils at 70degreesIf you have 500ml of each at a temperature of 20degrees which liquid would require most heat energy to make it boil?
The water will be require more water because it needs 80degrees more heat than the alchohol which only needs 50degrees more heat.
Does milk boils faster than water?
Water boils faster
