The temperature should be 885K.

Explanation:

In this case we use Charles's Law according to which the volume and temperature of a certain amount of gas are related, keeping the pressure constant. We convert the unit of temperature from Celsius to Kelvin: 0 = 273K - > 40 ° C = 40 + 273 = 313K

V1 / T1 = V2 / T2

2,3L/313K = 6,5L/T2

T2=6,5L / (2,3L/313K) = 884, 56K
