Conservation of Mass and Energy

Front

What does the Law of Conservation of Mass state?

Back

In a closed system, mass remains constant; it cannot be created or destroyed.

Front

Give an example of the Law of Conservation of Mass in everyday life.

Back

Burning a piece of paper demonstrates the conservation of mass, as the mass of the products equals the mass of the reactants.

Front

What is the Scientific Method?

Back

A systematic approach used by scientists to investigate and understand the natural world.

Front

What are hypotheses in the scientific method?

Back

Proposed explanations or predictions that can be tested through experimentation or observation.

Front

How does the scientific method help in understanding natural phenomena?

Back

It provides a systematic approach to studying and explaining natural phenomena.

Front

What is energy conservation?

Back

Energy conservation refers to the principle that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of energy transformation?

Back

When a battery-powered toy car moves, chemical energy in the battery is transformed into kinetic energy.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion.

Front

Define potential energy.

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the relationship between mass and energy in the context of conservation?

Back

Mass and energy are interchangeable; according to Einstein's equation E=mc², mass can be converted into energy and vice versa.
