Analysts expect gas prices to decrease or remain mostly flat not only in 2014‚ but for years to come. Nonetheless‚ drivers in some states will see higher prices at the pump‚ starting January 1. Gas prices may not have seemed all that cheap in 2013. But in fact‚ prices for the year as a whole were less expensive than they have been. According toAAA’s year-end report‚ American drivers paid $3.49 per gallon of regular‚ on average for 2013. That’s the cheapest per-gallon average since 2010; the national

Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than
