The Law of Conservation of Mass tells us that "mass can neither be created nor destroyed." Ever wondered what happens to matter during a chemical reaction? 🌍
A system is a defined space where matter and energy are studied. There are two types: open and closed systems. Can you guess how they differ? 🤔
Think about pouring a hot drink into a mug. The heat escapes, cooling the drink. This is an open system! Heat and matter can enter or leave the system. 🥤✨
Imagine a thermos flask keeping your drink hot. No heat or matter escapes—this is a closed system. It’s almost isolated from its surroundings. 🔒🔥
In a chemical reaction, the mass of reactants equals the mass of products. For example, 150g of clay becomes a 150g pot. Mass just changes form! 🍶🔄
