How is the can in the pan of water similar to the mercury barometer?
Both the can in the pan of water and the mercury barometer function based on the principle of atmospheric pressure. In both cases, changes in atmospheric pressure will cause a corresponding change in the level of water or mercury in the device. The height of the water or mercury serves as an indicator of the atmospheric pressure at that moment.
What is the relationship of boiling point with atmospheric 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.
What four things affect pressure?
Change in volume - container getting bigger or smaller with same amount of air; Change in temperature - air gets hotter or colder causing it to expand or contract; Change in density - air is pumped into or out of a fixed container.
Two factors that are responsible for a phase change?
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
What is a mercury barometer?
A mercury barometer is a device used to measure atmospheric pressure. It consists of a glass tube filled with mercury, with one end submerged in a mercury bath. Changes in atmospheric pressure cause the level of mercury in the tube to rise or fall, which can be used to determine the current pressure readings.
Can outdoor Christmas lights explode due to atmospheric 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.
what main factors cause the air in earths atmosphere to move?
uneven heating by the sun causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

Is atmospheric pressure at sea level constant 1013?
It isn't constant anywhere, no. 1013.25 mb is simply the average pressure, which is particularly important at sea level because that is how observations are standardized. But atmospheric pressure always varies no matter where you are, as a consequence of having weather.
What is the best cause of atmospheric pressure?
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)
What is cause of atmospheric pressure?
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.
What is the relationship of boiling point with atmospheric 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.
Which factor causes atmospheric pressure?
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.
Can your head explode in space due to the lack of atmospheric pressure?
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.
What four things affect pressure?
Change in volume - container getting bigger or smaller with same amount of air; Change in temperature - air gets hotter or colder causing it to expand or contract; Change in density - air is pumped into or out of a fixed container.
Why CO2 gas comes out in force when bottles of soda is opened?
The cause is the pressure difference between the gas pressure in the bottle and the atmospheric pressure.
Two factors that are responsible for a phase change?
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
