Answer:
B
Explanation:
From charles' law,
![v \alpha t](https://tex.z-dn.net/?f=v%20%5Calpha%20t)
where v is volume and t is absolute temperature
![\frac{v1}{t1} = \frac{v2}{t2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bv1%7D%7Bt1%7D%20%20%3D%20%20%5Cfrac%7Bv2%7D%7Bt2%7D%20)
![v1 = 0.5l \\ t1 = (22 + 273 )k\\ t2 = (4 + 273)k \\ t1 = 295k \\ t2 = 277k \\ \frac{0.5}{295} = \frac{v2}{277} \\ v2 = 277 \times \frac{0.5}{295} = 0.47l](https://tex.z-dn.net/?f=v1%20%3D%200.5l%20%5C%5C%20t1%20%3D%20%2822%20%2B%20273%20%29k%5C%5C%20t2%20%3D%20%284%20%2B%20273%29k%20%5C%5C%20t1%20%3D%20295k%20%5C%5C%20t2%20%3D%20277k%20%5C%5C%20%20%5Cfrac%7B0.5%7D%7B295%7D%20%20%3D%20%20%5Cfrac%7Bv2%7D%7B277%7D%20%20%5C%5C%20v2%20%3D%20277%20%5Ctimes%20%5Cfrac%7B0.5%7D%7B295%7D%20%20%3D%200.47l)
- Hence that's it
