Poverty imposes far-reaching hardships, not only on the poor but on all who share their communities. Virginia has a relatively low poverty rate -- it was again ranked 9th in the nation in 2013 â but it, too, has been affected by recent trends, with more than 1 in 10 residents now living below federal poverty thresholds. Virginia continues to work to make education and opportunity available to its at-risk populations.
Boyle's Law: The Pressure-Volume Law. Boyle's law or the pressure-volume law states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant. PV = C. When pressure goes up, volume goes down. When volume goes up, pressure goes down.
For an ideal gas, the pressure is inversely proportional to the volume of the container. Mathematically, we can express this by saying that the pressure is equal to a constant times one over the volume or that the pressure times the volume equals a constant.
