What happens if you Add equal amounts of water to each carton every 23 days to 2 cartons?

If you add equal amounts of water to each of the two cartons every 23 days, the water levels in both cartons will increase consistently over time. This will maintain the same ratio of water between the two cartons, assuming they started with equal amounts. The overall impact on the contents of the cartons will depend on what is already in them; the addition of water may dilute any substances present or affect their properties. Ultimately, both cartons will remain comparable in terms of water content.
