How does an increase in altitude affect the climate?

Answers

Answer:

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

What is the difference in the number of neutrons between an atom of fluorine and an atom of argon?
I need an answer fast PLEASE!

Answers

Flourine has 10 and argon has 8 the difference is 8

The difference between the number of neutrons between an atom of fluorine and an atom of argon is 12

The number of neutrons is obtained by subtracting the number of protons from the mass number of the atom. We can calculate the number of neutrons in each element given this information

Mass number of fluorine = 19

Atomic number of fluorine = 9

Mass number of Argon = 40

Atomic number of argon = 18

Hence;

Number of neutrons in fluorine = 19 - 9 = 10

Number of neutrons in argon = 40 - 18 = 22

Difference between number of neutrons in argon and number of neutrons in fluorine = 22 - 10 = 12
