Answer:

The final temperature is 806.226 degrees celcius.

Explanation:

It is given that initial conditions are as follows,

<em>Initial volume = 425 ml</em>

<em>Initial temperature =- 12 degrees celcius = 261 K</em>

<em>Initial pressure =788 mmHg</em>

The final conditions are as follows,

<em>Final volume = 2.4 liters</em>

<em>Final pressure = 577 mmHg</em>

<em>Final temperature = "T"</em>

<em>Let R be universal gas constant, n be number of moles..</em>

The ideal gas equation, is as follows,

(pressure)(volume) = (number of moles)(R)(temperature)

The number of moles remain constant in the process,

so equating <em>initial number of moles = final number of moles</em> , we get

\frac{(788)(425)(10^{-3}}{261} = \frac{(577)(2.4)}{T}

T = 1079.226 K = 806.226 degrees celcius
