An instant cold pack sold in pharmacies contains a packet of solid NH4NO3 surrounded by a pouch of water. When the packet of ammonium nitrate is broken, it dissolves in the water and becomes very cold. Explain, in terms of molecules and ions, why this process is thermodynamically favorable. Please answer this question with full explanation and reference to get full credit

0:00 Hello everyone.

00:01 So according to the question, i would like to explain over here.

00:04 And instant, we have an instant cold pack of a solid, which is in the pharmacist, it's going to be contained a solid.

00:16 Nh4, no3, it's going to be surrounded by the pouch of water.

00:21 So here we need to explain why when the packet is going to be ammonium nitrate is broken, the solid of water had become a very cold.

00:29 So why? happen we need to explain the term of molecules and ion and why this process is thermodynamically favorable so let us move to the solution part so i would like to explain over here and ammonium ammonium nitrate is actually consists of what it's consists of ionic bond packing ionic bond packed tightly together packed tightly tightly together with each other.

01:06 So when they are coming a contact with water, then they are come in to contact with what with water water.

01:26 So the water we are knowing that what is going to be happening.

01:30 The polar water molecule polar water molecules interfell they will start the interference with what with those ions those ions and eventually make them what disperse so i would like to write this part so that is what it's going to be happening and the taken energy whatever the taken energy it's having right take energy it take energy to do this which is observe why i would like to write which is actually absorbed from where from the surrounding itself and make the solution what and that is going to be make the solution cold while we can say the heat is going produce when heat is produced when the ammonia when the ammonium nitrate iron is going to be with interact with what water molecules so here the exothermic reaction is going to be happened and because of that the heat is going to be produced over here so i would like to write it this part when yeah so that is what we can say exothermic reaction is going to be happening and i would like to share one more point over here it is a lot less that it is lot less then what is needed in the water...
