You start at sea level on the beach in California. What would the atmospheric pressure be? Then you move to Los Angeles where the altitude is 87 meters above sea level what happens to the boiling point?
At sea level the pressure is 760 mm Hg if that is standard.
The boiling point of a liquid (I assume that's your question) decreases with altitude.
To determine the atmospheric pressure at sea level, you can use the standard atmospheric pressure value, which is approximately 1013.25 hPa (hectopascals) or 1 atmosphere (atm). This value represents the average atmospheric pressure at sea level.
Moving to Los Angeles, where the altitude is 87 meters above sea level, the atmospheric pressure will slightly decrease compared to sea level. According to the standard atmospheric pressure lapse rate, the pressure decreases by about 1 hPa every 8.3 meters of ascent. Therefore, at an altitude of 87 meters, we can estimate the atmospheric pressure to be slightly lower than at sea level.
As for the boiling point, it is directly influenced by atmospheric pressure. As you ascend in elevation, the atmospheric pressure decreases, and this affects the boiling point of liquids. At higher altitudes, where the atmospheric pressure is lower, liquids boil at lower temperatures. This occurs because the boiling point of a liquid is the temperature at which its vapor pressure is equal to the atmospheric pressure surrounding it.
In this case, as you move from sea level to an altitude of 87 meters in Los Angeles, the boiling point of water and other liquids will decrease slightly due to the slight reduction in atmospheric pressure. However, the decrease in boiling point may not be noticeable or significant at such a small change in elevation.
