Law of conservation of Matter

State the Law of conservation of Matter. Apply this law to a daily situation to explain the law.

  1. The Law of conservation of matter states that matter is neither created nor destroyed, but it is transfered. Ex: When an animal cease to exist, some of it's fat and muscle later becomes nutrition for its predator. And anything that is left becomes food for microbes and fungi. Sooner or later, nothing of that animal will remain, but will be used somewhere else...or better yet recycled.

  2. The law of conservation of mass statest he total mass of the reacting substances is equal to the total mass of the products of a chemical reaction, Mass can be neither created nor destroyed, and matter can be neither created nor destoyed during a chemical reaction. If you burned a sheet of paper it changes from paper to ash, carbon dioxide, and water vapor. if you captured all of these things then the mass of the products before and after the paper was burned the mass will be the same.

  3. Briana, you understood the law very well. Make sure to include the matter in your example to discussion.

  4. Morgan,

    Your example reflected the concept very well and you are able to apply the law into your example too. Express your example in terms of simple word equation to prove the law.

  5. The Law of Conservation of Matter states that matter can not be created nor destoryed,but it is combined nad rearranged in different ways. An example of the Law of Conservation of Matter is condensation. It is the process by which a gas is changed into a liquid. Just because the gas is changing its form, doesn't mean that the matter is being destoryed nor created. It is just combining and rearranging in different ways.

  7. The Law of conservation of matter states that matter is neither created nor destroyed, but it is transfered. So basically, it means that no matter how many chemical stages a substance goes through, the matter/mass will be the same. This implies that for any chemical process in a closed system, the mass of the reactants must equal the mass of the products. For example, the melting of gold.

  8. The law of conservation of matter states that matter can not be created nor destroyed. But can be rearranged in space or changed into a different substance. For example, you can have a cup of ice.A few hours later the ice is melted and now is water. Therefore, the mass of both the water and ice are equal/the same.

  9. the law of conservation of matter states that matter cant be created or destroyed. Example: the water on earth is constant it cant be created or destroyed. when water evaporates it goes into the sky and condenses into a cloud. the water is still there not destroyed but its just in a different state.

  10. the law of conservaion of mass states in any chemical or physical reaction mass can not be created nor destroyed. one example that apllies to this law is the melting of a candle. before and after melting, the mass of the candle and wax are still the same.

  11. The law of conservation states that matter can't be created nor destroyed but transfered. For Example, melting of ice. when the substance changes its state it is still water.

  12. The Law of Conservation of Mass stated that during a physical or chemical reaction mass can not be created or destroyed, but it can be transferred. The weight of the reactant the you start of with has to have the same mass after the reaction. An example of that is the melting sugar the matter changes from solid to liquid, but the mass of the melting sugar remains the same.

  13. Most of you picked up the melting ice to water as an example. What can be done during this melting process to prove the law. basically I am asking you to mention how can you prove the law for the example you mentioned in your response.

  14. the law of conservation of matter states that the mass of a substance remains constant over time during a chemical reation. matter can neither be created nor destroyed, it is just transferred from one substance to another. if 5grams of hydrogen reacts with 10grams of oxygen then the product would be 15grams of water.

  15. matter insnt created nor destroyed. ex... would be that water evaporating the matter is neither loss or gained

  16. The Law of conversation of matter explains that matter can't be destroyed but you can change matter's state. This means that matter can be transformed. An example of law of conversation of matter is a candle. Though it burns and melt, the mass continues to be the same. Another example is when an ice cube melts. The ice cube turns into a liquid and when it gets heated it becomes a gas.

  17. The law of conservation of matter states matter that matter can not be created nor destroyed. Ex. an ice cube melting and turning into a liquid.

    The law of conservation basically says that mass can be neither created or destroyed but you can change the matter's state.(solid, liquid, gas, plasma) An everday example of this is the freezing of ice cubes. It has to first start of as water and then it turns into a solid. The mass is still the same in both states because no water has evaporated, it has just frozen into a solid.

  19. The law of conservation is when you cant create or destroy mass, but you change the state of it.This applies to daily life because the food you eat is converted into energy to replace cells like your skin cells.If you weigh yourself at the same time everyday, you will have the same weight.

  20. The law of conservation states that matter cannot be neither created or destroyed, but it can transform. When I think of this law and how it occurs in our everyday life many things come to my mind, but the thing that sticks out is the freezing,melting, and/or boiling of water. The matter is not being destroyed and matter is not being created, but it is in fact transforming.
