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)
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.
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.
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.
Two key factors that cause atmospheric pressure to change are altitude and temperature. As altitude increases, atmospheric pressure decreases because there is less air above exerting force. Additionally, temperature affects pressure; warmer air expands and becomes less dense, leading to lower pressure, while cooler air contracts and increases density, resulting in higher pressure. These variations contribute to weather patterns and atmospheric dynamics.
Atmospheric pressure increases when the weight of the air above a specific point increases, often due to cooler temperatures that cause air to become denser. Additionally, high-pressure systems, which are typically associated with descending air, can lead to increased atmospheric pressure. Conversely, atmospheric pressure decreases when warm air rises, creating low-pressure areas. Weather patterns and altitude also influence local atmospheric pressure variations.
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.
The best atmospheric pressure for the human body is around 1013 millibars or 1 atmosphere. This pressure allows our lungs to easily expand and contract for breathing, and it supports the normal functioning of our circulatory system. Any significant increase or decrease in atmospheric pressure can lead to discomfort or health issues.
