Law of Conservation of Matter

What is the Law of Conservation of Matter?

• Matter cannot be created or destroyed, only changed in form

• Matter can be created and destroyed

• Matter is always conserved in chemical reactions

• Matter is only conserved in physical changes

Who first formulated the Law of Conservation of Matter?

• Albert Einstein

• Antoine Lavoisier

• Isaac Newton

• Marie Curie

In which century was the Law of Conservation of Matter established?

• 17th century

• 18th century

• 19th century

• 20th century

How does the Law of Conservation of Matter apply to chemical reactions?

• The total mass of reactants equals the total mass of products

• The mass of reactants is always greater than the mass of products

• The mass of products is always greater than the mass of reactants

• The mass of reactants and products can vary

Which of the following is an example of the Law of Conservation of Matter?

• Burning wood results in ash and smoke

• Water evaporating into steam

• Ice melting into water

• All of the above

How does the Law of Conservation of Matter relate to recycling?

• Recycling transforms waste into new materials without losing matter

• Recycling creates new matter from waste

• Recycling destroys waste matter

• Recycling has no relation to the conservation of matter

What role does the Law of Conservation of Matter play in environmental science?

• It helps understand the flow of matter in ecosystems

• It is irrelevant to environmental science

• It only applies to chemical industries

• It is only used in physics

How does the Law of Conservation of Matter affect the food chain?

• Matter is transferred through different trophic levels

• Matter is created at each trophic level

• Matter is destroyed at each trophic level

• Matter is irrelevant to the food chain

What is a common misconception about the Law of Conservation of Matter?

• Matter can be created in nuclear reactions

• Matter is always visible

• Matter can be destroyed in chemical reactions

• Matter is only conserved in closed systems

How does the Law of Conservation of Matter apply to the water cycle?

• Water is conserved as it changes states

• Water is created during evaporation

• Water is destroyed during precipitation

• Water is only conserved in oceans
