1st law of thermodynamics - Study guides, Class notes & Summaries

1st law of thermodynamics - Energy cannot be created or destroyed 2nd law of thermodynamics - Every energy transfer or transformation increases the entropy of the universe. Acids - pH less than 7 Adhesion - attraction between molecules of different substances all atoms want... - to be neutral (P=e-) and to have a full valence shell (8) Anabolic - complex molecules made from simple atomic mass - Number of protons + neutrons atomic number - the number of protons in the nucleus of an atom ...

4 basic laws of thermodynamics correct answers zeroth law: states that 2 objects in thermodynamic equilibrium with a 3rd object are also in equilibrium with each other 1st law: states that neither mass nor energy can be destroyed; only converted from 1 form to another(conservation of energy) 2nd law: states that the entropy of an isolated system can only increase; heat is not transferred from low temp system to a higher temp system one unless additional work is done 3rd law: states that...

energy - capacity to do work Compare potential energy and kinetic energy. Classify different energy forms into one of these two categories - potential energy is the possibility to do work: -chemical potential -concentration gradient -gravitational -stored mechanical kinetic energy -electrical -sound -radiant -thermal -motion Explain why cells need energy? Describe the types and examples of cellular work. - 1. synthetic work 2. mechanical work 3. concentration work 4. electrical ...
