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.
The relationship for Boyleâs Law can be expressed as follows: P 1 V 1 = P 2 V 2, where P 1 and V 1 are the initial pressure and volume values, and P 2 and V 2 are the values of the pressure and volume of the gas after change.
