- 1what is the law for the conservation of energy, explain?The law of conservation of energy states that the total amount of energy in a system remain consistent.
The law means that when energy is being used it is not being used up, instead it is being changed from one form to the other. - 2Identify a better word for 'lost' in energy conservationTransformed
- 3list and describe energy transformationEnergy can be changed from one form to another this is called ENERGY TRANSFORMATION.
some examples are
1. Chemical transformation
2. Electrical transformation
3. Radiant transformation - 4Describe energy transformationchemical energy is the result during a chemical reaction, chemical energy is stored in the bonds of the atoms and molecules that make up a substance
EXAMPLE
1. Wood to Coal - 5Describe electrical transformationIs the energy carried by moving electrons in an electric conductor
- 6Describe radiant energyAtoms absorb energy from an outside source and releases(off emit) this energy as electromagnetic radiation
- 7Use the particle model to explain the transmission of sound waveswaves in which the medium move at right angles to the direction of the waves are called TRANSVERSE WAVES
Waves in which the medium moves back and forth in the same direction as the waves is called COMPRESSIONAL WAVES (or longitudinal) - 8—
