Hey!!!...Here is ur answer
8. Room temperature = 25° C
for changing in kelvin we added 273
So the value of kelvin temperature will be= 273+25=298 kelvin
10. (i) The temperature of water remains constant during boiling bcoz the boiling point of water is 100° C and once it reached at 100° C after that it vaporise only...this is the reason why the temperature of water remains constant during boiling.
10 (ii) . Evaporation is a surface phenomenon bcoz bcoz it occurs in the surface and it is a layer to layer phenomenon.
Hope it will help you
