Question

when the temperture is increased surface tension of water a)increases b)decreases c)remains constant d)show irregular behaviour

Answer 1

b)DECREASES

Answer 2

glt hai

Answer 3

ni sai h when we heat urface tension of water decreases as water molecules tries to get its size smaller to reduce the effect of heat

Answer 4

rehne de heena agr nhi pta to glt mt btaya kr

Answer 5

arey its right mene parha h 11 m!!!!!!!!!

Answer 8

my ans is correct :P

Answer 9

heehhe ........the concept is that as the temperature increases the forces of attractios between the molecules are weakend

Answer 10

tikh h na ans to sai diya na bs resaoning ulti likh di (:

Answer 11

chl theek hai ab medal lena hai

Answer 12

ni ji rhne do :P

Answer 13

surface tension is the tendency for molecules in the SURFACE to contract to occupy less surface area so when u heat up a media u are increasing kinetic energy of molecules spreading them wide apzart
