Ideal gas equation:

$\overline{){\mathbf{P}}{\mathbf{V}}{\mathbf{=}}{\mathbf{n}}{\mathbf{R}}{\mathbf{T}}}$

P_{2} = 2atm

T_{2} = 800 K

P_{3} = 1 atm

T_{3} = ?

The volume of the tank does not change. The gas occupies the tank completely.

A tank is filled with an ideal gas at 400 and pressure of 1.00 .

Having been heated to 800 , at some point the tank starts to leak. By the time the leak is repaired, the tank is only half full, and the pressure of the remaining gas is again 1.00 . What is the temperature of the gas?
