Question

If atmospheric pressure increases by an amount p, which of the following statements about the pressure in a lake is true? (There could be more than one correct choice.) The absolute (total) pressure does not change. The absolute (total) pressure increases, but by an amount less than p. The absolute (total) pressure increases by p. The gauge pressure increases by p. The gauge pressure does not change.

The absolute (total) pressure does not change.

The gauge pressure does not change.

The absolute (total) pressure does not change.

The absolute (total) pressure increases, but by an amount less than p.

The absolute (total) pressure increases by p.

The gauge pressure increases by p.

The gauge pressure does not change.

Explanation / Answer

c)the absolute pressure increases by p as

absolute pressure = gaguge pressure+ atmospheric pressure

e)the gauge pressure does not change

hence option c and e are correct
