What is a single transformation?
The process of burning fuels is known as
What is combustion?
The total kinetic and potential energy of the particles in an object that may move and cause friction create this kind of energy
What is thermal energy?
The type of energy related to an object's weight and height is known as
Forms of energy associated with the particles of objects include thermal energy, electrical energy and these three other types of energy
What are chemical energy, nuclear energy and electromagnetic energy?
Describe the five types of energy transformations that occur in a car engine according to our reading
1. Electrical Energy produces spark which transfers to thermal energy. 2. Thermal energy releases chemical energy in fuel. 3. Chemical energy becomes thermal energy. 4. Thermal energy is converted to mechanical energy that moves the car. 5. Thermal energy is also converted to electrical energy to produce more sparks
What 6 energy transformations take place to use a hair dryer?
1. Sun transforms nuclear energy to electromagnetic energy. 2. Electromagnetic energy is transformed to chemical energy in plants that become fossils. 3. Coal is burned which is chemical energy. 4. Chemical energy from coal/steam transforms to thermal energy. 5. Thermal energy moves turbines--which is mechanical energy. 6. Mechanical energy is transformed to electrical energy which is used in a hairdryer.
Energy that is stored in the nucleus of an atom is known as this
