Water is polar, with the oxygen slightly negative and the hydrogens slightly positive (approximately 5 kcal/mole). Hence, individual water molecules are attracted to each other (+/-) and orient according to their dipole moment.
This attractive force must be overcome by applying heat in order to separate the molecules (heat of vaporization).
Petrol is nonpolar, so the only attractive force that must be overcome is the much weaker Van Der Waals force (an induced dipole moment).
What else can I help you with?
What evaporates first petrol or water and why?
Well... Only water can evaporate. So, the water and the water that is in the coke will evaporate at the same time, but the other substances in Coke besides water will remain put. I hope that answers your question.waterthe presence of sugar in coke elevates its boiling point. Actually, coke has a great deal of water in it. If you are talking about room temperature evaporation (or even evaporation by boiling as the first author writes about), the water component will vaporise first, leaving a sugar and other additive residue which will not evaporate unless much higher temperatures are used, eventually leading to the decomposition (not evaporation) of the sugar component.
Which evaporates faster hot water or cold water?
Hot water. Higher temperature means more kinetic energy, and energy is needed to change phases from liquid to gas (evaporation.)
Water evaporates more from areas near the equator or ares near the north and south poles?
Water evaporates more from areas near the equator.
Can fire make water evaporate?
Water evaporates more rapidly when it is hot; so, yesfire will increase evaporation.
When some water evaporates from a sugar solution the solution becames...?
The solution become more concentrated in sugar.
At what temperature does water evaporate more rapidly?
Water evaporates more rapidly at higher temperatures.
Do water evaporates more rapidly in the sun?
yes, yes they do
Does warm water evaporate more rapidly then cold water?
Yes, because when water evaporates it is usually warm when the sun is up and shining - so warm water evaporates more quickly than cold water because it is warm.
Does petrol or spirit evaporate faster?
Petrol evaporates faster than water at room temperature. this is because the boiling point of petrol is 95oC and water's boiling point is 100oC. As the boiling point of water is higher than that of petrol, petrol evaporates faster as it achieves its boiling point before water does.

Why is Puerto Rico so humid?
Puerto Rico is surrounded by the warm waters of the semi-tropical Caribbean Sea, and water evaporates more rapidly when the water is warm, so there is a lot of evaporation.
Why does water evaporate answer in short?
Water evaporates because its molecules gain enough kinetic energy to escape into the air as water vapor. This process occurs when the temperature of the water reaches a certain point, causing the molecules to move more rapidly and break free from the liquid surface.
Does rainwater evaporates more on a summer day or cold day?
Rain water evaporates more on a summer day.
Water evaporates more from areas near the equator or ares near the north and south poles?
Water evaporates more from areas near the equator.
How does having more water change temperature?
It changes because water evaporates. When it evaporates it makes it humid around it. It gets warmer.
Can fire make water evaporate?
Water evaporates more rapidly when it is hot; so, yesfire will increase evaporation.
