A 15.0 L tank of gas is contained at a high pressure of
Inessa05 [86]

Answer:

20.5 torr

Explanation:

Given parameters:

Volume of tank  = 15L

Pressure of tank  = 8.2 x 10⁴torr

Volume of empty chamber = 6.0 x 10⁴L

Unknown:

New pressure of the gas in this chamber = ?

Solution:

To solve this problem, a good knowledge of the gas law will suffice here. Since pressure and volume relationships are under consideration, the Boyle's law is the proper gas law to apply.

 Boyle's law states that "at constant temperature, the volume of fixed mass of gas is inversely proportional to the pressure of the gas".

Mathematically;

    (Pressure x volume) of tank  = (Pressure x volume ) of empty chamber

      15 x 8.2 x 10⁴   = Pressure of empty chamber x 6 x 10⁴

 Pressure of empty chamber = 20.5 torr

The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation
Bad White [126]
<span>This is due to the fact that the air pressure in that certain section of Earth’s atmosphere decreased. As density of gas particles decreases as air pressure decreases. Therefore, density of gas particles and air pressure have a direct relationship. An increase in air pressure would then effect to an increase in gas particles. </span>
