What is the general law of thermodynamics?
1st Law of Thermodynamics - Energy cannot be created or destroyed. 2nd Law of Thermodynamics - For a spontaneous process, the entropy of the universe increases. 3rd Law of Thermodynamics - A perfect crystal at zero Kelvin has zero entropy.
What is DQ in thermodynamics?
du = dq − dw. where dq is the differential increment of heat added to the system, dw the differential element of work done by the system, and du the differential increase in internal energy of the system. This is a statement of the First Law of Thermodynamics.
