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.
This means that as the pressure decreases, the volume increases, and as the pressure increases, the volume decreases. One way to think of this is if you push on a gas by decreasing its volume, it pushes back by increasing its pressure. This relationship is called Boyleâs Law and makes up part of the ideal gas law.heory When the volume of a gas shrinks, the gas molecules have less space to move around and so they hit their container more often. The more frequently the gas impacts the container walls, the higher the pressure. So, as volume decreases, the pressure increases.
