Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower at higher altitudes. This lower pressure decreases the boiling point of water. At sea level, the atmospheric pressure is greater, causing water to boil at 100 degrees Celsius.
Atmospheric pressure decreases with increasing altitude because the weight of the air above decreases as you move higher up in the atmosphere. At sea level, there is more air above you pressing down, resulting in a higher atmospheric pressure compared to the top of a mountain 5000m above sea level where there is less air above pressing down.
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
When the water level is higher inside than outside the flask, the gas pressure in the flask is lower than the atmospheric pressure. This is because the weight of the column of water inside the flask creates an additional pressure on the gas inside, reducing its pressure relative to the atmospheric pressure outside.
A barometer measures atmospheric pressure, which decreases with increasing altitude. At sea level, the weight of the air above exerts more pressure on the barometer compared to the top of a mountain, where there is less air above. This difference in pressure causes the barometer to have a higher reading at sea level than at the top of a mountain.
Water boils faster at sea level because there is higher atmospheric pressure, which increases the boiling point of water. At higher altitudes, such as on top of a mountain, the lower atmospheric pressure causes water to boil at a lower temperature, which means it takes longer to boil.
Water boils at a lower temperature on a mountain top due to lower atmospheric pressure at higher altitudes. This means that water will boil faster on a mountain compared to sea level where the pressure is higher.
Atmospheric pressure decreases as you go from the top of a mountain to sea level. This is because there is less air above you at higher altitudes, leading to lower pressure. Conversely, at sea level, more air is pressing down from above, resulting in higher atmospheric pressure.
Water would boil higher at the top of a mountain than at sea level. This is because there is less atmospheric pressure at higher elevations.

This is because the boiling point of any fluid increases as the pressure acting on it is increased. Atmospheric pressure on top of a mountain is lower than normal atmospheric pressure. Conversely, by not allowing steam to escape, the pressure above the water in a pressure cooker is allowed to build up to a much higher level.
Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower at higher altitudes. This lower pressure decreases the boiling point of water. At sea level, the atmospheric pressure is greater, causing water to boil at 100 degrees Celsius.
When the water level is higher inside the flask than outside, the gas pressure in the flask would be lower than the atmospheric pressure. This is because the water exerts a partial vacuum on the gas in the flask, reducing its pressure compared to the external atmospheric pressure.
Atmospheric pressure decreases with increasing altitude because there are fewer air molecules pressing down from above. This results in lower air density and a decrease in pressure at higher elevations such as the top of a mountain compared to sea level.
It would be more difficult to draw soda through a straw on top of a mountain because the atmospheric pressure is lower at higher altitudes, making it harder to create the suction needed to pull the liquid up the straw. In contrast, at sea level with higher atmospheric pressure, it would be easier to draw soda through a straw.
Atmospheric pressure decreases with increasing altitude because the weight of the air above decreases as you move higher up in the atmosphere. At sea level, there is more air above you pressing down, resulting in a higher atmospheric pressure compared to the top of a mountain 5000m above sea level where there is less air above pressing down.
No, the boiling point of a liquid is actually higher at sea level compared to on a mountain. This is because higher elevations have lower atmospheric pressure, which causes liquids to boil at lower temperatures to compensate for the decreased pressure.
