ΔG > 0
is always true for the freezing of water.
Explanation:
- The freezing of water is only spontaneous when the temperature is fairly small. Over 273 K, the higher value of TΔS causes the sign of ΔG to be positive, and there is no freezing point.
- The entropy decreases as water freezes. This does not infringe the Thermodynamics second law. The second law doesn't suggest entropy will never diminish anywhere.
- Entropy will decline elsewhere, provided it increases by at least as much elsewhere.
Deductive reasoning involves making broad observations and examining possibilities to reach a specific, logical conclusion, which is required in the formation of a hypothesis. Conversely, inductive reasoning involves taking specific observations and making broad generalisations from these. Therefore the answer is A.

One mole Hydrogen need 1/2mol O_2 .
Moles of Hydrogen
Moles of O_2
The distance covered by each atom of copper will be twice the radius of each atom, which is its diameter
it will be like as shown in diagram....
Let the number of atoms required is "n"
thus total atoms required will be
Let us convert pm to mm for unit cancellation.
Thus
hence
