Considering Gay-Lussac's law, a gas exerts a pressure of 4.00 atm at 1,092 K.

<h3>Gay-Lussac's law</h3>

Gay-Lussac's law states that the pressure of a gas is directly proportional to its temperature: when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, gas pressure decreases.

Gay-Lussac's law can be expressed mathematically as follows:

\frac{P}{T}=k

where P= pressure, T= temperature, k= Constant

This law states that the ratio of pressure to temperature is constant.

Studying an initial state 1 and a final state 2, it is fulfilled:

\frac{P1}{T1}=\frac{P2}{T2}

<h3>Final temperature</h3>

In this case, you know:

  • P1= 1 atm
  • T1= 273 K
  • P2= 4 atm
  • T2= ?

Replacing in Gay-Lussac's law:

\frac{1 atm}{273 K}=\frac{4 atm}{T2}

Solving:

T2\frac{1 atm}{273 K}=4 atm

T2=\frac{4 atm}{\frac{1 atm}{273 K}}

<u><em>T2= 1,092 K</em></u>

Finally, a gas exerts a pressure of 4.00 atm at 1,092 K.
