Airplane cabins are typically pressurized at 0.67 atm, and assuming the temperature inside an airplane is about the same as inside a potato chip processing plant, by what percentage has the bag "puffed up" in comparison to when it was packaged?

Explanation:

Assuming the pressure inside the packet at the time of packaging,

Given that there is no temperature difference between the air inside the pack and the cabin.

Using mathematical expression of Boyle's law:

where subscripts 1 & 2 denote the initial and final conditions respectively.

Now change in volume:

Now the % increase in volume:

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
