hydroelectric plants produce inexpensive electric power, the H₂
can be made industrially by the electrolysis of water.
(a) How many coulombs are needed to produce 3.5x10⁶ L of H₂
gas at 12.0 atm and 25^oC? (Assume that the ideal gas law applies.)
(b) If the coulombs are supplied at 1.44 V, how many joules are
produced?

Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
