Question

At which of the following temperature, the value
of surface tension of water is minimum ?
(a) 4°C (b) 25°C
(c) 50°C (d) 75°C

Answer 1

Answer:

d)75 degree Celsius

The surface tension water decreases with increasing temperature at near about 75degree celcius the surface tension of water is minimum. Answer: At 75 degree Celsius the surface tension of water will be minimum

Answer 2

calm water with 7 cm submerged. When a man stands on the raft, 8.4 cm are submerged, the man's mass is
