As I read the question, I have this creepy feeling like there's a picture
of some kind that's supposed to go along with it, to show us what
"this point" means. Without a peek at the pic, there's no way to start
answering the question.
The weight of air is called atmospheric pressure. It is the force exerted by the weight of the air above a given point in the atmosphere.
Weather is the state of the atmosphere at a given time and place, including temperature, humidity, precipitation, wind speed, and cloud cover.
A given point of x and y
It is the temperature at which the element will change state from a solid into a liquid. Note that the temperature actually changes depending on pressure. When no pressure is given assume 1 atmosphere.
In mathematics, an accumulation point is a point such that every neighbourhood of the point contains at least one point in a given set other than the given point.
A spherical surface, with its center at the given point, and its radius equal to the given distance.
They form the sphere whose center is the given point and whose radius is the given distance.
That's a "circle". The given distance is the circle's radius, and the given point is the circle's center.
a circle, centered at the given point.
Boiling point is when the liquids pressure equals the pressure of the atmosphere.
The boiling point of water at one atmosphere of pressure is 373.15 K.
The set of all points a given distance from a center point is a circle. The given distance is the radius, and the given point is the center. Or, in 3 dimensional space, a sphere.
