Answer:

800.3 Kelvin

Step-by-step explanation:

127°C = 400.15 Kelvin (because 127 + 273.15)

Charles Law:


(V1)/(T1) = (V2)/(T2) Thus,
(10.0 L)/(400.15 K) = (20.0 L)/(T2)

Then, work out the math algebraically.

T2 = 20.0 / (10.0/400.15)

= 20.0 / 0.02499...

= 800.3 Kelvin

This is assuming the pressure remains constant.
