Explain law of conservation of mass class 9
WebFigure 2. Angular momentum is conserved for orbital systems. This keeps the angular momentum about the star constant by adjusting the variables of v v and r r for the angular momentum equation below: L=mvr L = mvr. This scenario of orbiting objects is discussed with more detail in the next lesson. WebSep 23, 2024 · The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example—in Figure 2.2.3 —when wood burns, the mass of the soot, ashes, and gases equals the original mass of the wood and the oxygen when it first reacted. Figure 2.2.3: Image of the wood courtesy of Ehamberg and …
