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).

Can fire make water evaporate?
Water evaporates more rapidly when it is hot; so, yesfire will increase 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.
When water is heated the water molecules gain and move more rapidly?
yes they do
What evaporates faster a cup of water by the sun or a cup of water boiled?
a cup of water that is boiled since it gives more heat.
When water evaporates from the leaves more water moves up through he plant to replace the lost water in the process called?
Capillary action
Do water evaporates more rapidly in the sun?
yes, yes they do
Can fire make water evaporate?
Water evaporates more rapidly when it is hot; so, yesfire will increase evaporation.
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.
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.
Solute dissolves more rapidly when?
solute dissolves more rapidly in hot water
Why does water evaporate quicker than water?
The warmer water is, the more quickly it evaporates.
Which liquid evaporates more quickly water or juice?
Water evaporate faster.
What happens when water becomes more hot and humid?
It evaporates. :)
