Just as water pressure is caused by the weight of water, atmospheric pressure is caused by the weight of the air. Pg. 126 Conceptual Physical Science 4th Edition.
Atmospheric pressure will typically not cause outdoor Christmas lights to explode. Atmospheric pressure in most areas is typically not high enough to cause such lights to explode.
Gravity. Atmospheric pressure is the weight of a column of air. Of course, the temperature of that air changes it's density and therefore it's weight (i.e. pressure)
The boiling point of a substance decreases as the atmospheric pressure decreases. This is because lower atmospheric pressure reduces the pressure pushing down on the liquid, making it easier for the liquid to vaporize. Conversely, higher atmospheric pressure increases the boiling point of a substance as more pressure is needed to overcome the atmospheric pressure and cause the liquid to vaporize.
Atmospheric pressure is primarily caused by the weight of air above a specific point on the Earth's surface. Gravity pulls air molecules towards the Earth, creating a force that results in atmospheric pressure.
Yes, gauge pressure includes atmospheric pressure. Gauge pressure is the pressure measured above atmospheric pressure, so it accounts for the atmospheric pressure as a reference point.
Gauge pressure is the pressure measured relative to atmospheric pressure, while atmospheric pressure is the pressure exerted by the Earth's atmosphere on a surface. Gauge pressure accounts for atmospheric pressure, while atmospheric pressure is the total pressure exerted by the atmosphere.
Yes, in space, the lack of atmospheric pressure can cause a person's head to explode if they are not wearing a pressurized suit to maintain the necessary pressure around their body.
The cause is the pressure difference between the gas pressure in the bottle and the atmospheric pressure.
Atmospheric pressure
isobars are a measure of atmospheric pressure. variations in atmospheric pressure basically cause weather - high pressure vs low pressure, etc.
Atmospheric pressure decreases as you climb a mountain because there is less air above pushing down on you. This decrease in pressure can cause symptoms like shortness of breath and fatigue at high altitudes.
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
