HESS'S LAW in Thermodynamics

In this Thermodynamics (Chemistry) video in Hindi for Class 11 we explained what Hess's law of Constant Heat Summation is.
Using Hess's law the reaction enthalpy for a reaction can be found out using reaction enthalpies of some other reactions.
Hess’s law : If a reaction takes place in several steps then its reaction enthalpy is the sum of the enthalpies of the intermediate reactions, provided that all of the reactions are carried under the same condition.

Glad to see that you are active again sir! thank you so much!!

[@TheRealAbhimanyu]

Thank you 🙏🙏❤🙏🙏 you so much sir for Everything.

[@Atharv7478]

Sir I am student of class 10 sir I was just watching your videos on structure of atom and I have a doubt on that and that is that a wave is associated with every particle (matter wave) I have a doubt that in which medium is the matter wave travells in as waves need a medium to travel and every medium has it's own basic property like electromagnetic field have it's property in which electromagnetic waves can only travel at CONSTANT speed and that is speed of light (c) then what is the CONSTANT speed of matter waves and in which medium these matter waves travels in.
Sir please clear my doubt.

[@ojasgupta0202]

Sir I have the same doubt also that which medium is required by matter wave to propagate?

[@mamoonaijaz2638]

As you considered the matter waves, so the media required for their propagation must be matter i.e. solids, liquids and gases are the media (medium) for matter waves

[@Atharv7478]

@@mamoonaijaz2638 But what happens when a particle moves in vaccum then now where the matter waves travels?

[@MinakshiBhandari-b4r]

Thank you sir🎉

[@artisharma....]

Please help sir 🙏🙏🙏
Sir I have a doubt that i=√-1
i²=-1... and so on but no one tells about i⁰ mean i power zero is it not define or something else
