6. Do you think that the volume control on an audio amplifier is calibrated in intensity or intensity level? In other words, if you turn your stereo half way down, have you cut the power in half or cut the decibel level in half? Explain.

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.
