Which of the following statements is not true with regards to the first law
of thermodynamics?
A
The first law of thermodynamics states that within an open
system, the total energy of that system will remain constant.
B
A change in internal energy E) can be calculated if you know
how much energy was transferred in the form of heat, and how
much energy was used or created in the form of mechanical
work (w).
•
With regards to heat flow (q), if a system is heated, the energy
will move from the surroundings to the system.
D
You can calculate the change of enthalpy (AH) of a system (the
change in the heat content of the system) by calculating the heat
flow of the system. The heat flow is represented by the letter (q).
