Well, isn't that a happy little thought! If the pressure inside a nebula were greater than the force of gravity, it might cause the nebula to expand and disperse into the surrounding space. Just like a gentle breeze carrying flower petals through the air, the nebula's beautiful gases could drift away and create new wonders in the cosmos. Remember, in the vast universe, there's always room for new beginnings and endless possibilities.
It is balanced by radiation pressure, and gas pressure.
The inward force of gravity is counteracted by two outward forces: gas pressure, and radiation pressure. Once the star runs out of fuel, the radiation pressure stops, the gas pressure is no longer enough to counteract gravity, and the star collapses - into a white dwarf, a neutron star, or a black hole, depending on its mass.
The larger the object, the more 'space' is displaced, and thus, the greater the gravity. The Moon displaces less 'space' than the Earth, so the Moon has less gravity. The space station displaces very little space AND its' shape does not lend itself to taking advantage of the spacial displacement, so it doesn't result in very much gravity. Stand in a swimming pool and hold a beach ball under the water: the pressure of the water on the ball is a simulation of gravity. Hold a tennis ball under the water: far less pressure, yes? Now, hold something with the exact same collective mass as the beach ball (lets say one of those 'noodle' things the kids play with) and you'll have far less pressure on it than on the beach ball. Why? It has the same mass as the beach ball, so why isn't there the same amount of pressure (gravity) on it? Because the 'shape' of it does not lend itself to take advantage of the gravitational pressure. Gravity can, however, be simulated with inertia. If the ship spins... centripical force and all that.
Earth's atmospheric pressure is measured as 1 bar. Jupiter's atmospheric pressure is 100 million bars. Therefore, it is 100 million times greater
The balloon would expand due to the lack of atmosphere on the moon, but it wouldn't burst because the pressure inside the balloon would equalize with the low pressure outside. Additionally, the balloon would float in the lower gravity environment of the moon.
Think about this: if the pressure WERE equal, what would happen in the instant when you open the neck of the balloon and whatever pressure is on the inside meets the pressure that is on the outside (atmospheric pressure)? In your experience, what DOES happen?
You explode. Because the pressure inside the body is much greater than outside the body, the body expands until it explodes outwards.
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.
It is balanced by radiation pressure, and gas pressure.
earth's gravity
Okay i think i might know but i'm not sure but i think this can never happen because if it did the atmospheric pressure would crush us. our fluids in our bodies exert pressure on the atmospheric pressure(the same amount) and pretty much neutralize the effect!
Inside a star, the force of gravity is balanced by the pressure generated from nuclear fusion reactions occurring in the star's core. These nuclear reactions create an outward pressure that counteracts the force of gravity trying to collapse the star. This delicate balance between gravity and pressure determines the size, temperature, and lifespan of a star.
Gravity affects all objects regardless of whether they are inside a balloon or not. However, the air pressure inside the balloon might counteract the effects of gravity for a short period, but ultimately gravity will cause the balloon to fall.
Air pressure - greater on inside than out.
In the vacuum of space, the marshmallow would expand as the pressure inside the marshmallow is greater than the pressure in space. Eventually, the water inside the marshmallow would start to boil off, causing it to dehydrate and turn into a crispy, dried-out marshmallow.
The pressure inside the container would decrease.
When a cup is flipped upside down, the water remains inside due to air pressure. The pressure pushing down on the water is greater than the force of gravity pulling it out of the cup, creating a seal and preventing the water from falling out.
