Why does atmospheric pressure change with altitude and how can you explain this phenomenon?
Atmospheric pressure decreases with altitude because there is less air above pushing down on the air below. As you go higher in the atmosphere, the air becomes less dense, leading to lower pressure. This can be explained by the gravitational force of the Earth pulling the air molecules towards the surface, creating higher pressure at lower altitudes.

Explain why atmospheric pressure does not burst an inflated balloon?
An inflated balloon is made of elastic material that can expand without bursting when subjected to increased pressure, such as atmospheric pressure. The elasticity of the balloon allows it to stretch and accommodate the higher pressure while retaining its shape. Additionally, the pressure inside the balloon may equalize with the atmospheric pressure, preventing it from bursting.
What is the significance of the adiabatic gradient in the study of atmospheric science?
The adiabatic gradient is important in atmospheric science because it helps us understand how temperature changes with altitude in the atmosphere. This gradient helps explain the behavior of air parcels as they rise or sink, which is crucial for predicting weather patterns and understanding atmospheric dynamics.
What is the relationship between altitude and air pressure to explain why rescue helicopters have a difficult time flying at altitude over 6000m.?
The higher you are from the Earth's surface - the lower the air pressure is. Helicopters are heavy machines - requiring a huge amount of effort from the rotor blades to keep it airborn. The lower the air-pressure, the harder the rotors have to work to keep the craft flying.
Explain why air has pressure?
The simplest explanation is that air is composed of gases. Gases are composed of molecules. Molecules have mass. The closer molecules get to the center and bottom of the gravity well, the more closely packed they become, because successive "layers" pack down on those below, piling up. The weight of the gases on top of those on the bottom compress those on the bottom.
How do scientists explain the phenomenon of particles popping in and out of existence?
Scientists explain the phenomenon of particles popping in and out of existence through the concept of quantum fluctuations. In the quantum world, particles can briefly appear and disappear due to the inherent uncertainty and fluctuations in energy levels. This phenomenon is a fundamental aspect of quantum mechanics and is supported by experimental evidence.
How you will you explain pressure belts and winds diagram?
The Coriolis effect explains this phenomenon clearly. Pressure belts and wind belts differ in patterns depending on certain atmospheric factors like temperature.
If you boil water at the top of a mountain would you expect it to boil at 100 degree Celsius explain?
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
What effect on air pressure with altitude explain briefly?
As altitude increases, air pressure decreases. This is because the higher you go, the less air there is above you pressing down. The decrease in pressure with altitude follows a logarithmic pattern, with the rate of decrease slowing down the higher you go.
If you performed a melting point experiment in the laboratory and on the top of the mountain would your results differ explain?
Yes, the results could differ because the atmospheric pressure varies with altitude, which can affect the boiling point of liquids, including the melting point of solids. The lower atmospheric pressure at the top of a mountain can cause the melting point of a substance to be slightly lower than at sea level.
What is the relationship between altitude and air pressure to explain why rescue helicopters have a difficult time flying altitude above 6000 m?
An inverse relationship.
Explain why atmospheric pressure does not burst an inflated balloon?
An inflated balloon is made of elastic material that can expand without bursting when subjected to increased pressure, such as atmospheric pressure. The elasticity of the balloon allows it to stretch and accommodate the higher pressure while retaining its shape. Additionally, the pressure inside the balloon may equalize with the atmospheric pressure, preventing it from bursting.
What does a compound pressure gauge measure?
A compound pressure gauge measures both positive and negative pressures relative to atmospheric pressure. It typically consists of two pressure sensors, one for measuring positive pressure (above atmospheric pressure) and one for measuring negative pressure (below atmospheric pressure). This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.
What is the significance of the adiabatic gradient in the study of atmospheric science?
The adiabatic gradient is important in atmospheric science because it helps us understand how temperature changes with altitude in the atmosphere. This gradient helps explain the behavior of air parcels as they rise or sink, which is crucial for predicting weather patterns and understanding atmospheric dynamics.
State and explain how the boiling point of water will change if the atmospheric pressure falls?
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
Explain why it snows in Kenya?
altitude.
A blown up balloon is carried up a high mountain will it get bigger or smaller explain why its volume changes?
As balloons increase in altitude, there is less atmospheric pressure pushing on it, so the result is that the balloon expands. The opposite is true, if you sink a balloon in water there is more pressure on the outside of the balloon so it shrinks.
How do you explain the appearance of goosepimples chickenskin during sneezing?
The pressure from the sneeze forces carbon dioxide into your pores, causing them to expand, giving the goosepimple chickenskin phenomenon. -Dr. Bryan
