Chemical Reactions
Chemical energy is the energy stored in the chemical bonds of a substance
What is chemical energy?
Law of Inertia
What is Newton’s Second Law of Motion?
Direct current, alternating current
Name two types of currents
A wave in which the vibration of the medium is parallel to the direction the wave travels.
What is a longitudinal wave?
Chemical reactions involve the breaking of chemical bonds in the reactants and the formation of chemical bonds in the product
How do chemical reactions involve energy?
This law states that energy cannot be created or destroyed, only transferred or transformed.
What is the law of the conservation of energy?
Resistance
What is the process of current slowing down
An area of a longitudinal wave where the particles of the medium are spread out.
What is rarefaction?
The law stating that mass is neither created nor destroyed
What is the law of conservation?
This type of energy is stored in food and fuels like gasoline.
What is chemical energy?
Insulator
What is material through which charge cannot flow easily?
The interaction that occurs when a wave bounces off a surface that it cannot pass through.
What is reflection?
Involving the breaking of chemical bonds in the reactants and the formation of chemical bonds in products
What are chemical reactions?
This is the equation used to calculate kinetic energy.
What is KE=1/2mv2
Series, parallel
Name two main circuit types?
A change in sound frequency caused by motion of the sound source, motion of the listener, or both.
What is the doppler effect?
Synthesis reactions, competitions reaction, single placement reaction, double replacement reaction, and combustion reactions
What are the five general types of reactions?
This type of energy transfer occurs through empty space and does not require matter unlike conduction or convection.
What is radiation?
Net Electric Charge
What happens with an excess or shortage of electrons.
A wave that appears to stay in one place and does not seem to move through a medium.
What is a standing wave?
