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.
