Symbol inquiry

Postby Vana Mirzakhani 3I » Wed Feb 06, 2019 8:47 pm

Does change in U = internal energy or does just U by itself = internal energy? I am confused as to which symbol is the correct one to represent internal energy? Thank you.

Internal energy is represented by "U", and change of internal energy is represented by "ΔU"
the delta symbol (Δ) always represents a change in something

The symbol U represents internal energy which is just the total store of energy in a system. Change in internal energy is equal to the work of a system.

Change in internal energy: ΔU
Internal energy: U

"U" is the variable that represents the actual internal energy of a system. While "△U" represents the change in the internal energy of a system.
