In plants and trees, water travels upward through the roots and stems due to: (THERE ARE TWO ANSWERS) A) Adhesion B) Cohesion C) Precipitation D) Oxidation
any idea ? what function (rol ) may be the water ?
i know it's not C. but honestly i have no idea what the other words mean. first quiz on online school and we have no learning material to go along with it ..
A. can be ?
huh
may be cohesion rol function ?
what does rol mean
a tip of role
function
what
for plant ,tree life
i think B. cohesion make sens - my opinion -
It has much to do with the properties of water, which @jhonny9 started out in explaining: cohesion, and also adhesion. Due to the intermolecular forces in water (LDF, but most importantly, Hydrogen bonding and dipole dipole interactions), water has the tendency to attach to other water molecules, and also attach to other unlike molecules. This leads way to a property of water called adhesion and cohesion. Organisms like plants and trees take advantage of this in their vascular system.

(These are due to the van der waal interactions) Precipitation - I think in different fields there are different meanings. But since this is under the subject 'chemistry', precipitation probably regards to precipitation reactions. These are where reactions of aqueous species condense to solid products that are insoluble. Oxidation - This probably refers to redox reactions, and oxidation is a half reaction. This is where an electron is transferred to a different component.
ah, thank you, was clueless on those definitions. then it's adhesion and cohesion
