Your Aunt Sally knows that you're taking an environmental science course and says she has a question for you, "What does it mean
when environmentalists say we need to reduce consumption of disposable goods, since there really is no 'away' to throw things?" To help her understand the science behind the issue, you explain the a) Second Law of Thermodynamics b) Competitive Exclusion Principle c) First Law of Thermodynamics d) Principle of Conservation of Matter
According to the law of conservation of matter, matter is the substance which ac not be created and even it can not be destroyed , hence we need to have the same number of atoms before and after the reaction constant during a chemical change or process of chemical as were number of atoms and type of atoms present before the chemical change .
Hence , from the options , the correct answer is the Principle of Conservation of Matter .
The ecliptic plane is inclined at 23.5° with respect to the celestial equator because of the tilt of the Earth's rotation axis with respect to the plane of its orbit around the sun.
