PV=kT
Since P is constant,
V/T = k/P is constant
if V is decreased by a factor of 361/400, T must decrease by the same factor to have the quotient remain constant.
298.15 * 361/400 = 269.08K
It seems odd that the temperature goes down as the gas is squeezed, but remember that we are keeping a constant pressure.
