Sure! Here are the answers to your questions:
1. In the case of the 'Deepwater Horizon' explosion, approximately 4.9 million barrels of oil leaked into the ocean. This incident occurred in 2010 in the Gulf of Mexico and resulted in one of the largest environmental disasters in history. The oil spill had significant impacts on marine life, coastal ecosystems, and local economies.
2. The term 'hydrophobic' refers to a molecule or substance that repels or does not mix well with water. In simple terms, "hydro" means water, and "phobic" means fear or aversion. Hydrophobic substances tend to gather together and exclude water molecules, forming droplets or beads. For example, when water is poured onto a hydrophobic surface, it beads up rather than spreading out. This property is commonly seen in materials like oil, wax, and certain plastics.
