Answers

Answered by naimuddinsheikh354

Answer:

Parachor is a quantity (related to surface tension) defined according to the formula: P = γ1/4 M / d. where γ is the surface tension, M is the molar mass, and d is the density.

STALAGMOMETER IS USED TO MEASURE SURFACE TENSION OF LIQUIDS USING "DROP WEIGHT" METHOD. SAMPLE OF LIQUID IS PLACED IN UPPER TUBE SO AS TO FILL TUBE TO PREDETERMINED LEVEL, & ALLOWED TO RUN DOWN LOWER TUBE UNTIL DROP FALLS OFF
