Which of these have an effect on air pressure?
Temperature, altitude, and humidity all have an effect on air pressure. As temperature increases, air pressure decreases, while air pressure decreases with increasing altitude. Humidity can also affect air pressure by directly influencing the density of the air.
Why low pressure air spirals upwards?
The causality is the other way round: air spirals upwards and BECAUSE of that there is low pressure on the ground. The question should be WHY does the air rises upwards and WHY does it spiral? The spiralling comes from the coriolis effect. The rising comes from differences in mass density (lower density rises above higher density). That density difference may come from temperature differences. High pressure areas have the contrary effect: air falls down and causes high pressure on the ground.
Describe the effect of temperature on density currents?
As temperature decreases, the density of water increases, causing it to sink. This creates a density current, where denser, colder water sinks below warmer water. The movement of these currents plays a significant role in ocean circulation and the mixing of nutrients and gases in water bodies.
Does wind blow from areas of high pressure to low pressure or low pressure to high pressure?
To give a simple answer the wind blows from High Pressure to Low Pressure. But I am afraid it is not quite as simple as that, otherwise when you looked at a weather map you would see the wind arrows going directly from a High (Anticylone) to a Low (Cyclone). Due to the rotation of the earth a rotational effect (Coreolis effect) acts on the winds so that even though the wind would like to flow directly from High to Low the coreolis effect acts on the wind to make it rotate round a High pressure region clockwise (In the Northern Hemisphere) and anticlockwise round a Low (again in the Northern Hemisphere) just like the water going down a plughole. So in effect the wind will travel from High to Low but in rather a convoluted route dictated by rotation of the earth and the relative positions of the Highs and Lows.
Atmospheric serpuser is detemined by the temperature and density of the air and the amount of water vapor in it?
Yes, atmospheric pressure is determined by the combined effect of temperature, air density, and the concentration of water vapor present in the air. These factors influence the overall molecular motion and interactions within the atmosphere, directly impacting the pressure exerted by the air at a given location.
How is it that the altitude decrease and the density of the air does what?
Altitude decreases, pressure increase, temperature decreases (some, but less effect than pressure), density goes up.
What effect does air density have on the absorption and radiation of energy?
An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
What is the effect of temp on density?
An increase in temperature results in a decrease in density.
What effect does size have on density?
Size and Density are different aspects of an object or material. Size describes how much 3-dimensional space an object occupies. This can be described by simple terms of length, width, and/or height, or as volume. Density refers to the mass of a material found in a specific volume. In general, one does not have an effect on the other
What is the effect of a temperature decrease and a pressure altitude increase on the density altitude from 90 F and 1250 feet pressure altitude to 55 F and 1750 feet pressure altitude?
1,700-foot decrease.
What is the effect of shape on the density of samples of the same material?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
What happens to the density of gold when cooled?
The value of the density increase but the effect is without significance.
What are two things that effect density?
temperature and pressure
What maneuver to increase the thoracic pressure illustrates the effect of external factors on the venous pressure?
The Valsalva maneuver to increase thoracic pressure illustrates the effect of external factors on venous pressure.
How does increasing attitude affect air pressure and density?
as the altitude increase, the effect of gravity become more insignificant on air and the air become more disperse or thinner hence it does affect the air pressure and density by decreasing both air pressure and density of the air.
Which describes the effect or prolonged stress on blood pressure?
It causes blood pressure to increase.
What effect does pressure have on gas?
Increasing pressure on a gas will result in the gas molecules being pushed closer together, leading to an increase in the gas's density. This will also cause the gas to occupy a smaller volume. Additionally, higher pressure can lead to an increase in the rate of chemical reactions involving gases.
