Thermodynamics – is a brunch of physics which studies energy, its
transfer
from one place to another and its transformation from one form to another

Слайд 4ISOLATED SYSTEM
This system doesn’t exchange energy or matter with the surroundings.
Universe is considered to be an isolated system
Слайд 5CLOSED SYSTEM
A system, that doesn’t exchange matter but exchanges
energy with
the surroundings.
Слайд 6OPENED SYSTEM
A system, that exchanges both matter and energy with surroundings.
All
living organisms are opened systems.

Слайд 13BIOCALORYMETRY
Biocalorymetry – is a measurement of the energetics of biological processes
such as biochemical reactions, association of ligands to biological macromolecules, folding of proteins into their native conformations, phase transitions in biomembranes, and enzymatic reactions, among others.
