States Of Matter
What is an atom?
The basic unit from which all matter is made.
What is energy?
The ability to do work or cause change.
What is Mechanical energy
Energy an object has due to its motion, shape, position, or a combination of these factors.
What is the formula for Kinetic Energy?
Kinetic energy= ½ x Mass x Speed2
How are the particles in a solid?
Particles are packed very closely together.
What is a molecule?
A group of two or more atoms held together by a chemical bond.
What is motion?
An object is in motion when its position changes relative to another object.
What is nuclear energy?
Type of potential energy stored in the nucleus.
What is the formula for gravitational potential energy?
Gravitational Potential Energy= Weight x Height above ground
Describe a liquids particlez
Particles - Particles are closely in contact with one another.
What are elements?
Substances that are made up of only one type of atom.
What is force?
A push or pull (motion)
What is Electrical Energy?
Energy of electric charges.
What is the formula for power?
Power= Work/Time
Describe gas particles
Particles - Have space to move and fill all of the space available, gas is the same as the volume of its container.
What is a mixture?
Made up of two or more substances that are together in the same place, but their atoms are not chemically combined.
What is work?
Anytime you exert a force on an object that causes the object to change its motion in the same direction as you exerted the force.
What is Thermal Energy?
Total kinetic and potential energy of all particles of an object.
What is the formula for work?
Work = Force x Distance
What does a solid have?
Solid - has a definite shape and volume.
What is a compound?
A substance made of two or more elements that are chemically combined in a set ratio.
What is the formula for work?
Work = Force x Distance
What is Chemical Energy?
Form of potential energy that is stored in chemical bonds between atoms.
What is the formula for calculating pressure?
Pressure= Force / Area
What does a Gas have?
Liquid - no shape, definite volume
