Greater pressure is exerted inside the whale's body, particularly in the lungs, compared to the pressure outside the blowhole. When a whale surfaces to breathe, it rapidly expels air from its lungs, which is under higher pressure than the atmospheric pressure outside. This pressure differential allows the whale to forcefully expel water vapor and air through the blowhole.

Which has greater linear speed the horse near the outside rail of a merry go round or a horse near the inside rail?
the outside horse
What is special about the angler fishes body that it can withstand so much pressure?
Anglerfish have a gel-like substance in their bodies that helps them resist the crushing pressure of the deep ocean. Additionally, they have a specialized skeletal structure that supports their body and internal organs, allowing them to withstand the extreme pressure of their deep-sea environment.
What animals are soft and have no skeleton at all or outside shell?
Some animals that are soft and have no skeleton or outside shell include jellyfish, slugs, and sea cucumbers. These animals rely on other structures or mechanisms for support and movement, such as hydrostatic pressure in jellyfish and muscular contractions in slugs.
How do they stick on the wall?
A Plant SuckerA smooth surface is not entirely smooth. It has small grooves that can be grabbed by a plant stem (or the feet of small insects).A LollipopThe moistened sugar adheres to the surface.A Suction CupThe cup is compressed, and tries to expand back to its original shape. However, the flexing of the cup creates a partial vacuum under the cup, and the air is unable to pass between the smooth contact area. So the air pressure outside keeps the cup against the wall. (Moistening the rubber of the cup will provide a better seal.)
Do the zippers of half chaps go inside your leg or outside?
Outside
Is greater pressure exerted inside the whale's body or outside the blowhole?
Greater pressure is exerted inside the whale's body, as the lungs compress and force air out through the blowhole. When the whale surfaces to exhale, the pressure inside its body is released through the blowhole, creating the characteristic spout of mist or water vapor.
What is the pressure exerted on the outside of a can if the surface area of the can is 0.2 m2 and the force is 10N?
The pressure exerted on the outside of the can would be 50 Pa (P = F/A).
Why don't you feel the pressure exerted by the atmosphere?
You don't feel the pressure exerted by the atmosphere because your body is used to it and is able to balance the pressure inside and outside.
What is the pressure of air outside the body called?
The pressure of air outside the body is called atmospheric pressure. It is the force exerted by the weight of the air in the Earth's atmosphere on a surface.
What are the two types of outside pressures that may act on the outside of an organism?
Atmospheric pressure out side the body and hydrostatic pressure for animals that live in water
Explain in molecular motion how the air exerts pressure on the outside of the eye?
Air molecules are constantly moving and colliding with the surface of the eye. The impact of these collisions creates a force that is exerted on the outside of the eye, which we perceive as air pressure. The more air molecules collide with the eye, the higher the pressure exerted.
Is pressure internal or external?
Pressure can be both internal and external. Internal pressure refers to the force exerted by a fluid within a closed system, while external pressure can be the force exerted by a substance or object outside of the system onto the system.
What would cause a balloon to expand if taken to the of a mountain?
Lowered Pressure
When the air pressure in the lungs is greater than the air pressure outside the body you?
at higher altitudes the pressure of air is greater in our lungs as compare to the air pressure outside the body
Is the pressure of a balloon greater on the inside or outside?
The pressure of a balloon is greater on the inside because the gas molecules inside the balloon are constantly colliding with the walls of the balloon, creating the pressure that keeps the balloon inflated.
Is the pressure greater on the inside or outside of the plane?
the pressure is high out side the plane because the air moves around quickly.
What prevents mercury in the tube of a barometer from running out into the container at the bottom of the tube?
The top of a barometric tube is sealed leaving no place for air to escape. It works along the same principle as a drinking straw, but in reverse. In a drinking straw, the sucking motion reduces the pressure of the air inside the straw to a lower level than the air outside the straw. Liquid resists changes in volume due to pressure and is drawn up through the tube due to the air pressure exerted on the surface of the liquid outside the straw. In a barometric tube the tube is sealed at one end, trapping a finite amount of gas in the tube. The air pressure inside and outside the tube is equal, keeping the mercury suspended at a certain level. If the pressure outside is raised, more force is exerted on the surface of the mercury outside the tube than on the surface inside. This raises the level of the mercury in the tube until the pressure of the air is equalized -- there is still just as much air in the tube, but a smaller volume at a greater pressure.
