What happens to oak wood if left in water for 7 days?

If oak wood is left in water for seven days, it will absorb moisture, causing it to swell and potentially warp. Prolonged exposure can lead to structural weakening and an increased risk of mold or decay, especially if the water is stagnant. Additionally, the wood may develop a darker color due to prolonged saturation. After drying, the wood could return to its original shape but may have lost some of its strength.
