Respuesta
The final pressure of the gas when cooled from 500 K to 250 K, with the volume remaining constant, is 3 atmospheres.
Explicación
## Step 1The problem involves the application of Gay-Lussac's Law, which states that the pressure of a gas is directly proportional to its absolute temperature, provided the volume remains constant. This can be mathematically represented as:###
where
and
are the initial pressure and temperature, and
and
are the final pressure and temperature.## Step 2In this problem, the initial pressure
is 6 atmospheres, the initial temperature
is 500 K, the final temperature
is 250 K, and we are asked to find the final pressure
.## Step 3Substitute the given values into the Gay-Lussac's Law formula:###
## Step 4Solve for
by cross-multiplying and dividing:###
