why does methylated spirits evaporate faster than water?

Question

less surface tension - water has one of the most abnormally high levels of surface tension

For a general explanation on what determines vaopr pressure, see
http://www.timedomaincvd.com/CVD_Fundamentals/chemistry/volatility.html

Water has strong hydrogen intermolecular binding as well as a permanent dipole moment to keep the liquid phase intact and prevent evaporation. Most organic molecules do not have strong intermolecular binding, because of the strong internal carbon bonds. There are also entropy (S) issues, descibed in the reference.

Answer 1

It Shirnk Due To Exoosmosis.

Answer 2

Because In Heavy Water There Is Absence Of All Minerals Which Mostly Present In Mineral Water.So If We Drink Drinj Heavy Water Our Body Can Not Get Any Mineral. So We Cannot Survive.
