gayaneshka [121]

Answer:

New temperature = 546 K

Explanation:

Given that,

Initial volume, V = 200 L

Initial temperature, T = 273 K

We need to find the new temperature if the volume is doubled.

The relation between temperature and volume is direction. If volume is doubled, it means the temperature gets also doubled.

New temperature of the gas = 2(273) = 546 K
