Let's discuss this question.
00:03
So here we have the question that says when an ammonium nitrate is dissolved in water so the resulting solution feels cool to touch.
00:13
So here the question is this is because.
00:16
So here first statement is there is an increase in the entropy when the solution forms.
00:21
Second statement is the strength of attraction between the solute and solvent particle is greater than that of the attraction between the solute particles.
00:30
Third statement is there is a degrees in entropy when solution forms.
00:35
Fourth is the strength of attraction between the salute is equal between salute and solvent particles.
00:40
And then the last statement is the strength of attraction between the salute particle is greater than that of the attraction between the salute and solvent.
00:48
So here we can say when ammonium nitrate is dissolved in water.
01:10
So the solution feels cool to touch because it is an endothermic reaction.
01:47
So here the reason why the solution turns cool is because it is an endothermic reaction.
01:54
And here we can say means it would absorb the energy from.
02:15
The surrounding in the form of heat.
02:32
So here we can say it observes the energy from the surrounding.
02:37
And further here we can say that when the change is endothermic, so here will be positive.
03:03
That is basically we can say the entropy also increases so here we can say changes endothermic so the value of h will be positive here this will be positive and basically it means that the entropy will also increase so now let's move on to all the points so here the first point says that there is an increase in enthalpy when the solution formed...
