The main difference between a series and a parallel circuit is that
a. more components can be added to a parallel circuit.
b. the voltage source for a series circuit can be weaker.
c. in a series circuit there's only one path for current to flow.
d. a parallel circuit can handle components with higher resistances.

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.
