Science Laws

15 Points Per Correct Answer - No time limit  

1. His principle states that a system in equilibrium will shift in a direction that relieves a stress placed on the equilibrium. Equilibrium- a point in time when the forward and reverse reaction rate are equal. Stress- something that causes the equilibrium to move (heat, more reactants, pressure for gases, etc.). Boyle's Principle Matthew's Principle Avogadro's Principle Le Chatelier's Principle

2. One of the colligative properties, vapor pressure lowering, is based on this law. colligative properties- properties of solutions that have a greater effect when there is more solute than solvent. vapor pressure lowering- the boiling point is harder to reach because the gases above the solution press down less than the gases above a pure substance. Faraday's law Fermat's first law of molecules Raoult's Law James's law

3. This law states that the total enthalpy change of a complex reaction is equal to the sum of the enthalpy changes of each step. enthalpy- the change of heat/energy content in a system. An ice cube melting would show an increase in enthalpy (it's absorbing energy). complex reaction- a reaction with more than one step. Stanley's Law Hess's Law Mullikan's Law Garibaldi's Law

4. This law states that the entropy of a universe must always increase, even though the entropy of a system can decrease. entropy- the disorder of a system (a shuffled deck of cards is much more disorganized than a freshly opened pack). Zeroth Law of Thermodynamics Gunther's Law Urey-Miller Law Second Law of Thermodynamics

5. This law states that entropy of a pure substance at absolute zero is zero. Fundamental Law of Chemistry Scheele's Law Lavoisier's Relativity Law Third Law of Thermodynamics

6. His guidelines must be used to determine the ultimate cause of an illness in an organism. A serum from a sick organism is taken and placed into a healthy organism. When the healthy organism becomes ill, it must display the same symptoms as the old organism, and it must show signs of the same pathogen (infecting agent). Jenner's First Postulate Pasteur's Rules Koch's Postulates Salk's Law

7. Light was determined to be a massless particle holding great energy from this effect, which stated that particles could only absorb quantas (certain amounts) of energy. Planck's Effect Schrodinger's Effect Bohr's Effect Photoelectric Effect

8. It states that electrons in the same orbital must have opposite spins. orbital- a given area where electrons will "stay" most of the time. Pauli Exclusion Principle Aufbau Principle Hund's Rule Paschen's Principle

9. You cannot know both momentum and position of a particle at one time (Imagine a rolling ball caught in a picture and a ball sitting at that exact same spot). Heisenberg Uncertainty Principle Fundamental Problem of Physics Spontaneous Reaction Principle Ardinger's Movement Principle

10. This gas law states that gases at equal volumes, temperatures, and pressures have the same molar volume (they will have the same amount of molecules). Ideal Gas Law Boyle's Law Avogadro's Law Charles's Law
