425 ml of neon gas at -12°c and 788 mmhg
expands into a 2.40 l container while the
pressure decreases to 577 mmhg. what is the
temperature of the gas in °c?
enter the answer

The final temperature is 806.226 degrees celcius.

Explanation:

It is given that initial conditions are as follows,

Initial volume =

Initial temperature =

Initial pressure =

The final conditions are as follows,

Final volume =

Final pressure =

Final temperature = "T"

Let R be universal gas constant, n be number of moles..

The ideal gas equation, is as follows,

The number of moles remain constant in the process,

so equating initial number of moles = final number of moles , we get

= 806.226 degrees celcius
