The surface tension of cold water is that of hot water

The surface tension of pure water is

Assertion: Oil spreads on cold water . Reason : The surface tension of oil is graater than that of cold water .

Assertion: Oil spreads on cold water . Reason : The surface tension of oil is graater than that of cold water .

Surface tension of water at 0^@C is 75 dyne/cm, find the surface tension of water at 25^@C . (alpha for water = 0.0027//^@C )

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)

The surface tension of water at freezing point is

Statement-1: It is better to wash the clothes in cold soap solution. Statement-2: The surface tension of cold solution is more than the surface tension of hot solution:
