G = H - TS
if H < 0 , S>0 then G < 0 => spontaneous for all T
if H > 0, S < 0 then G > 0 => non spontaneous for all T.

surface tension
When water is filled carefully in a glass, one can fill it to a height h above the rim of the glass due to the surface tension of water. To calculate h just before water starts flowing, model the shape of the water above the rim as a disc of thickness h having semicircular edges, as shown schematically in the figure. When the pressure of water at the bottom of this disc exceeds what can be withstood due to the surface tension, the water surface breaks near the rim and water starts flowing from t...
class 10 electricity doubt ðŸ˜
shouldnt the total resistance here be 6ohms? cant the current just like short circuit and go before the 6ohm resistor (the ans is actually 1ohm and this q was asked in 2024 and m still not really able to understand this q even tho its been many days now)
