Re: internal energy
Internal energy is represented by delta U. Q represents the heat entering or exiting the system.

Re: internal energy
Yup, internal energy is the delta u = q + w. just remember, if the reaction has a constant volume, then no expansion work is done, and delta u is equal to q subscript v.

Re: internal energy
The change in internal energy is represented by delta(U). Delta(U) is equal to the energy transferred by heating (q) + the energy transferred by compression (w).
delta U = q + w
delta U = q + w

Re: internal energy
Calculating internal energy corresponds to the deltaU equation, where deltaU = q + w.
Re: internal energy
Delta U is the internal energy. Q represents heat. Utilizing the two is through the equation: Delta U = q + w where w is the net work.

This is good to note. Delta U is importantly not just internal energy but the change in internal energy. We are calculating the change, rather than the actual total internal energy of an entire system.

Re: internal energy
Also, heat and work are equivalent means of energy transfer and are the only to change the internal energy of a system.
