When air moves from an area of high pressure to an area of low pressure it causes:
a.) ran to fall
b.) an increase in temperature
c.) the wind to blow
d.) a decrease in temperature

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
