The gas in a sealed container has an absolute pressure of 125.4 kilopascals. if the air around the container is at a pressure of 99.8 kilopascals, what is the gauge pressure inside the container? a. 1.5 kpa b. 24.1 kpa c. 25.6 kpa d. 112.6 kpa e. 225.2 kpa

C. 25.6 kPa

Explanation:

Recall the last time you checked the pressure in your car tires. The gauge reading might have might have been 220 kPa.

If you think about it, the pressure inside the tire was the gauge pressure plus the external atmospheric pressure.

In words,

absolute pressure = gauge pressure + atmospheric pressure

In symbols,

   Subtract    from each side and switch

    Substitute values

= 125.4 – 99.8                                Do the subtraction  

genetic variation will increase because of a new habitat and food source.
