Due to its polarity, which is caused by hydrogen ends that are positive in comparison to oxygen ends that are negative, water molecules are attracted to one another, resulting in water having the highest surface tension.
Therefore, the correct option is (A): H2O
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
The liquid state of matter has the following properties:
