Would you expect higher atmospheric pressure on a dry day or a rainy day?

On a dry day, as clear skies are mostly associated with High pressure system, causing columns of air sinking, getting adiabatically warm and dry, while Low pressure systems are related to columns of rising air, yielding to adiabatically cooling, getting saturated, forming clouds, and if the conditions are achieved, causing precipitation, increasing the humidity.

When low pressure moves in air is converging at the surface and is flowing upwards and diverging aloft which allows for any warm, moist air at the surface to rise up and cool by expansion, forming clouds and precipitation. While most of the time low pressure is involved with rain, it can also rain when high pressure is around because the high pressure may be weak enough to allow for the rising of warm, moist air at the surface to be carried up and be cooled by expansion leading to cloud development and rain.

Sodium Hydroxide use boiling water why?
Boiling point is described as the point at which vapor pressure is equal to atmospheric pressure. Adding sodium hydroxide into boiling water would increase the boiling point of the solution (it would be a solution if you add the NaOH into it). This is due to the addition of ionic particles. The addition of ionic particles blocks the path for water molecules to escape from the solution. Therefore, it would take longer for vapor pressure to equal atmospheric pressure. Similarly, there would be a high boiling point in lower altitudes than in higher altitudes due to the differences in atmospheric pressure. In lower altitudes, it would be harder to reach boiling point due to more atmospheric pressure. Meanwhile, at higher altitudes, it would be easier to reach boiling point due less atmospheric pressure.
Is barometric pressure the same as atmosheric pressure?
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.
Why would water boil at less than 100 degrees on top of a mountain?
The boiling point of any liquid is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. So if the atmospheric pressure is lower, it will take a lower temperature to make the vapor pressure equal to that of atmospheric pressure. At hill-stations, the air is generally thinner due to the altitude and the atmospheric pressure is also lower. Here, it requires less than 100oC temperature to reach the point where the vapor pressure of water reaches that of air. So, water boils below 100oC at hill stations.
What instruments are used to measure the atmospheric pressure?
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.

What would occur when he atmosheric pressure is higher than intrapulmonary pressure?
When the atmospheric pressure is higher than intrapulmonary pressure pressure, inspiration will not take place.
Would you expect a higher atmospheric pressure at the top of mountain in Alaska's Denali national park or near sea level in Florida's everglades national park?
Since there is more air pressing down from upper levels of the atmosphere, Florida's Everglades park would have the greater atmospheric pressure

When a pressure is measured as 1016mb what does that mean?
That would be slightly higher than the 'normal' atmospheric pressure of 1013mb
If you boil water at the top of a mountain would you expect it to boil at 100 degree Celsius explain?
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
Would you expect the air pressure in a valley that's sea level to be higher or lower than air pressure at sea level?
I would expect it to be lower.
Would you expect the air pressure in the valley that's below sea level to be higher or lower than air pressure at sea level?
I would expect it to be lower.
Would you expect the air pressure in a valley that's below sea level be higher or lower than air pressure at sea level?
I would expect it to be lower.
Would you expect that the air pressure in a valley that's below sea level to be higher or lower than air pressure at sea level?
I would expect it to be lower.
What is the basic instruments for measuring atmospheric pressure?
Atmospheric pressure is measured by a barometer. There are several types. The one most likely to be found in a home is an anaeroid barometer.
What the basic instrument for measuring atmospheric pressure?
This would be a barometer. When the air pressure drops, you can expect rain or other bad weather like thunderstorms. On the other hand, when the air pressure rise, you can expect better weather. You can tell by using a barometer.
