Why is air preassuare greastest at the earths surface?
Air pressure is greatest at the Earth's surface because the weight of the air above exerts a force on the air below. As you move higher in the atmosphere, there is less air above pushing down on you, so the pressure decreases. At higher altitudes, there are fewer air molecules, resulting in lower air pressure.
Why does air pressure increase at lower altitudes?
Air pressure increases at lower altitudes because there is more air above pushing down on the air below. This higher pressure near the ground is due to the weight of the air column above pushing down on it. As you move higher up in altitude, there is less air above pushing down, resulting in lower air pressure.
Why does a balloon get smaller in cold weather?
The simple answer is because the pressure remains the same. When pressure remains constant, the change in volume will be directly proportional to the change in temperature. The air molecules release energy as they travel around inside the balloon. What we call pressure is technically the force of the air molecules colliding with the inside of the balloon and each other. The kinetic energy is related to the speed of the molecules. The faster the molecules are moving, the greater the kinetic energy. The greater the kinetic energy, the greater the pressure in the inside of the balloon. The outside air is doing the same thing to outside of the balloon. Therefore, the pressure pushing out is equal to the pressure pushing in. Temperature decreases because the molecules inside the balloon are releasing their energy in the form of heat as they interact with each other. In fact, they heat energy passes through the balloon and is absorbed by the air on the outside. Over time, more energy is released, and the temperature drops. The volume of the balloon decreases in order to maintain a constant pressure. As the surface area decreases, the total pressure pushing in also decreases so that it always equals the pressure pushing out.
What happens to the air pressure as you go higher?
Air pressure decreases as you move higher in the atmosphere. Air, just like any form of matter has mass, and when affected by earth's gravity, weight. The weight of air is pushing down on you with a force of 1 atmosphere at sea level. As you increase elevation the air pressure is reduced because there is less air to push down on you. Just like air, water pressure increases as you increase your depth in it, or any fluid.
What is the weight of the air pushing down on the earth?
The weight of the air pushing down on Earth's surface is due to air pressure, which averages around 14.7 pounds per square inch (psi) at sea level. This pressure is caused by the force exerted by the weight of the air molecules in the atmosphere above.
Why is atmospheric pressure greatest at the surface of earth?
Atmospheric pressure is greatest at the surface of the Earth because there is more air above pushing down. As you move higher in the atmosphere, there is less air above, resulting in lower atmospheric pressure. Gravity also plays a role in compressing the air molecules closer to the Earth's surface, increasing the pressure.
If the pressure of the gas pushing down on the liquid is 100 mmHg what will be the pressure of the dissolved gas molecules pushing up out of solution?
100
The force of air molecules pushing on an area?
Air pressure.
Water pressure is the greatest against submerged object sides of a submerged object same top?
Yes, the water pressure is greatest at the sides of a submerged object because the water depth is greatest there, resulting in more water weight pushing down. The pressure decreases as you move towards the top of the object because there is less water weight above pushing down.
What is a low-pressure system and what is a high-pressure system?
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
Where is fluid pressure the greatest?
Fluid pressure is the greatest at the deepest point. If the fluid is in different shaped vessels, the pressure is the greatest at the bottom of the vessel no matter what the shape.
What is the difference between a high-pressure system and A low pressure system?
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
What is the difference between high-pressure system and a low-pressure system?
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
What is the measure of the force with which air molecules are pushing on the Earth's surface?
Air Pressure
What is the measure of the force with which air molecules are pushing on the earth surface?
Air Pressure
Why does plasticine get longer when you roll it?
because it also gets thinner when you roll it. being plastic, the pressure of rolling shoves the molecules together, pushing molecules in the middle toward either end.
Why does the atmosphere exert pressure?
The atmosphere exerts pressure because of the weight of the air above pushing down on the air below. This pressure is caused by the force of gravity acting on the mass of the air molecules in the atmosphere.
