Verified answer

Enthalpy (H) is the sum of the internal energy (U) and the product of pressure and volume (PV) given by the equation:

H = U + PV

H is heat absorbed at const pr. U is change in internal energy ( ∆E ) and PV is work done on surroundings

Given, H = 22 j , PV = 41j

∆E = H- PV = 22- 41 = - 19 j

dE = q + w = + 412 - 358 = +fifty 4 J ability replace of the gadget: the gadget features fifty 4 J of ability. ability replace of our environment: our environment lose fifty 4 J of ability. ability replace of the universe: 0
