Enthalpy in Thermodynamics | explained in HINDI

In this Physics video lecture in Hindi we explained the basics of enthalpy of a thermodynamic system. Enthalpy is the heat content of that system, i.e., the amount of energy required to bring that system from absolute zero to the current state. It is the sum of the internal energy and the product of the pressure and the volume. H = U + PV. Here U is the internal energy reflecting the sum of the kinetic and the potential energy of the molecules. And PV indicates the energy required to create the current volume from nothing, i.e., energy required to make room for that space. In this video we also explained what happens to the enthalpy of a system in an isobaric and in an adiabatic process.

In the previous video we talked about Entropy.

फिजिक्स के इस वीडियो लेक्चर में हम बात करेंगे एंथैल्पी पर | एंथैल्पी होता है किसी थर्मोडायनेमिक्स सिस्टम का हिट कंटेंट अर्थात कुल कितना ताप एक थर्मोडायनेमिक्स सिस्टम में है | एंथैल्पी होता है किसी थर्मोडायनामिक सिस्टम का आंतरिक ऊर्जा तथा उसके चाप तथा आयतन के गुणनफल के बराबर |
