delta U equation

[005532550]

Is delta U equivalent to delta Ethermal and does it represent the conservation of energy? I'm thinking about this similarly to physics but I don't know if the two directly equate.

Hi! I'm not all too familiar with the notations of the First Law of Thermodynamics in physics terms, but delta H and delta E are interchangeable in terms of describing the conservation of energy in chemistry as ∆U = q+w or ∆E = q+w. Hope this helps!

Hi, delta U and delta E can be interchanged since they both represent the change in internal energy. In both cases, they are equal to q (heat added to system) - w (work done by system).

Hello! In a sense, delta U is equal to delta E; in fact, they are synonymous, meaning the two can be used interchangeably. Also, they describe the conservation of mass through the change of internal energy. Hope this helps!

Delta U and delta E can be used interchangeably because they both represent internal energy of a system
