Which step will decrease the pressure of a gas inside a closed cubical container? increasing the number of moles of gas decreasi

Jobisdone [24]

Answer: Decreasing the temperature inside the container will decrease the pressure of a gas inside a closed cubical container.

Explanation:

According to Gay-Lussac's Law : 'The pressure of the gas increases with increase in temperature of the gas when volume of the gas is kept constant'.

$(Pressure)\propto (Temperature)$

At constant volume, pressure of the gas will decrease on decreasing the temperature or vice versa.

Decreasing the temperature inside the container will decrease the pressure of a gas inside a closed cubical container.

A cylinder, with a piston pressing down with a constant pressure, is filled with 2.10 moles of a gas (n1), and its volume is 46.

olga2289 [7]

Answer:

The volume is $V_2 =15.33 \ L$

Explanation:

From the question we are told that

The number of moles of the gas is $n_1 = 2.10 \ moles$

The volume of the gas is $V = 46.0 \ L$

The of moles of the gas that leaked is $n_2 = 0.700 \ mol$

Generally from the ideal gas law

$PV = nRT$

Generally at constant pressure and temperature

$\frac{V}{n} = constant$

So $\frac{V_1 }{n_1} = \frac{V_2 }{n_2}$

=> $V_2 = \frac{ V_1 * n_2 }{ n_1}$

=> $V_2 = \frac{ 46.0 * 0.700 }{ 2.10 }$

=> $V_2 =15.33 \ L$
