11. COPY LIQUID PARTICLES

12. PROPERTIES OF LIQUIDS
SURFACE TENSION- AN INWARD PULL AMONG THE MOLECULES OF A LIQUID THAT BRINGS THE MOLECULES CLOSER TOGETHER.
EX- A FULL GLASS OF WATER CAN BE HIGHER THAN THE RIM.
VISCOSITY-LIQUIDS RESISTANCE TO FLOWING
EX- HIGH VISCOSITY- SLOW FLOW- HONEY
EX- LOW VISCOSITY- FAST FLOW- WATER
