2. SURFACE TENSION
• Surface tension : A streached membrane creat on the surface of
known a liquid is as surface tension.*
• surface tension is due to cohensive
• Unit = N/m²
3.
4. FACTOR AFFECT
SURFACE TENSION
• Factor affecting surface tensionAffect of temperature :) Temperature.
increase surface tension decrease.At value very high temperature the
value of surface tension is zero that is called critical temperature
• Effect of impurity.
• soluble impurity. - soluble impurity increase surface tension. Increase
• Insoluble impurity increase surface tension decreased.
• surface tension is independent to surface area.
