Answer:
The total pressure is
The temperature at the bottom is
Explanation:
From the question we are told that
The length of the glass tube is
The length of water rise at the bottom of the lake
The depth of the lake is
The air temperature is
The atmospheric pressure is
The density of water is
The total pressure at the bottom of the lake is mathematically represented as
substituting values
According to ideal gas law
At the surface the glass tube not covered by water at surface
Where is the volume of
At the bottom of the lake
Where is the volume of the glass tube not covered by water at bottom
and i the temperature at the bottom
So the ratio between the temperature at the surface to the temperature at the bottom is mathematically represented as
substituting values
=>
