Respuesta :
The law that allows calories to be determined by heat (energy) transfer from one substance to another, but it is never destroyed is first law of thermodynamics.
What is first law of thermodynamics?
Energy cannot be generated or destroyed, only changed in form, according to the basic law of thermodynamics.
- Energy transfer occurs when mass crosses the control boundary, external work is performed, or heat is transferred across the boundary in any system.
- These cause the stored energy in the control volume to shift.
Hence first law of thermodynamics justify the given statement.
