568 cm3 of chlorine at 25° C will occupy what volume at -25° C while the pressure remains constant?
The chlorine will occupy 473 cm³.
This is a Charles' Law Problem. You can read about Charles' Law at
In your question,
This makes sense. The final Kelvin temperature was about one-sixth lower than the initial temperature. The final volume should be about one-sixth (100 cm³) less than the initial volume.
Hope this helps.
