True or false: If the absolute pressure at a certain depth in Lake Michigan is 3.5 atmospheres, the gauge pressure at that depth is 4.5 atm.
Answer :- The given statement is FASLE.
Reason -: According to defition of gauge pressure," The gauge pressure is the difference between the absolute pressure at a point and the atmospheric pressure at same point.
Thus if absolute pressure , P = 3.5 atm
And we have atmospheric pressure at the same point is = 1 atm , therefore
Gause pressure at that point will be = 3.5 - 1 = 2.5 atm..
Any doubts leave a comment... THANKS
