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
=>
Answer:
when volume and the number of particles are constant
Explanation:
Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Gay Lussac's law is given by;
The ideal gas law is the equation PV = nRT
Where;
P is the pressure.
V is the volume.
n is the number of moles of substance.
R is the ideal gas constant.
T is the temperature.
Generally, raising the temperature of an ideal gas would increase its pressure when volume and the number of particles are constant.
This ultimately implies that, when volume and the number of particles are held constant, there would be a linear relationship between the temperature and pressure of a gas i.e temperature would be directly proportional to the pressure of the gas. Thus, an increase in the temperature of the gas would cause an increase in the pressure of the gas at constant volume and number of particles.
