A scuba diver descends to a depth of 20m. At that depth, thepressure is approximately A)atmospheric pressure.
B)twice atmospheric pressure.
C)three times atmospheric pressure.
D)four times atmospheric pressure.
Hint:
P = P0 + rho*g*h Do not forget P0, the atmosphericpressure.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
