Lance arrives early at the slc airport (with flowers and balloons in hand) to welcome home his "friend" from a mission. her plane is delayed. while waiting, he notices that it takes 2 minutes 47 seconds to get down the hall if he stands on the moving sidewalk. while walking on the floor (not on the moving sidewalk), it took him 93 seconds. if he walks while on the sidewalk how long will it take him?

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
