Which of the following statements is INCORRECT with reference to the first law of thermodynamics?
The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems.
First Law of Thermodynamics for a closed system undergoing a process neglecting kinetic and potential energy.
δQ = dU + δW
The heat added to the system has been considered to be a positive quantity.
Conversely, if heat were removed, then the heat would be a negative quantity.
Work done on the system = sign convention is -ve
Work done by the system = sign convention is +ve
Note that if no heat transfer occurs, the system is called adiabatic.
Work is also subject to a sign convention, which is work done by a system is positive work done on a system is negative
Heat or energy transfer to the system = sign convention is +ve
Heat or energy transfer from the system = sign convention is -ve
