The temperature at which the surface tension of water is zero
(1) `370^(@)C `
(2) `0^(@)C`
(3) Slightly less than `647 K`
(4) `277 K`

A temperature in 0^(@)C is converted into K

In which case K_(p) is less than K_(c) ?

Why temperature less than 0^@K is not possible ?

The surface tension of water at 0^(@) C is 75.5 dyn/cm. Calculate the surface tension of water at 25^(@)C .

Figure shows the cross section of a wall made of three layers. The layer thicknesses are L_(1), L_(2) = 0.750L_(1), and L_(3) = 0.350L_(1) . The thermal conductivities are k_(1), k_(2) = 0.900k_(1) , and k_(3) = 0.800k_(1) . The temperature at the left side and right side of the wall are T_(H) = 30.0^(@)C and T_(C)= - 15.0^(@)C , respectively. Thermal conduction is steady . (a) What is the temperature difference Delta T_(2) across layer 2 ( between the left and right sides of the layer ) ? If k_(2) were, instead, equal to 1.1 k_(1) , (b) would the reate at which energy is conducted through the wall be greater than, less than, or the same as proviously, and (c ) what would be the value of Delta T_(2) ?

At 4^(@)C, 0.98 of the volume of a body is immersed in water. The temperature at which the entire body gets immersed in water is (neglect the expansion of the body ) ( gamma_(w) = 3.3 xx10 ^(-4)K^(-1) ):-

The surface tension of water at 0^@C is 72 dyne/cm, surface tension of water at 30^@C is (alpha for water = 0.0025//^@C)

Regarding the surface tension property of liquids, the correct statements is/are a) surface tension decreases with increase of temperature b) at 20^@ C the surface tension of ethanol is greater than that of water c) the dimensions of surface tension is SI units is Nm^(-1) d) in the fine polishing of the glass, the edges become smooth due to surface tension
