C1 (b). 1.the value of surface tension (water)
in N/m
C1 (b). 2. the value of surface tension
(mercury) in N/m
Transcribed Image Text:C1 (b). 1.the value of surface tension (water) in N/m C1 (b). 2. the value of surface tension (mercury) in N/m
C1 (b). The capillary effect in a glass tube of
2.9 mm diameter, when immersed in (1) water
and (2) mercury are 5.4 mm and -3.1 mm
respectively. Calculate the value of surface
tension in contact with air for water and
mercury in N/m. Take, the contact angle for
water =0° and mercury =130°.
