liquids

kinetic molecular theory of liquids

intermolecular forces hold molecules tg

3 properties unique to liquids

1. capillary action

2. surface tnsion

3. viscosity

property of liquid not unique to liquids

vapor pressure

what do the properties of liquids depend on

strength of atraction between particles

cohesive forces

IMF among liquid molecules

adhesive forces

attractive forces ebtween molecules of a liquid and a surface (container)

droplet

cohesive forces minimize surface area (sphere)

capillary action

ability of a liquid to move up a narrow tube or a porous material due to forces of cohesion and adhesion

viscosity

measure of liquid resistance to flow or thickness

related to ease in which molecules can move past each other

how does viscosity change with IMF and temp

increase with stronger IMF

decrease with higher temp

surface tension

amount of energy required to stretch surface of a liquid by a unit area

surface tension of water

7.29 × 10^-2J/m²

what causes surface tension

net inward force experienced by molecules on surface of a liqudi

how does IMF determines urace tension

higher imf→higher surface tension
