Physical and chemical changes
Anything that has mass or takes up space.
What is matter?
A path that is made for an electric current.
What is a circuit?
A measure of the extra positive or negative particles that an object has.
What is a charge?
When matter changes from a liquid to a solid.
What is the freezing phase?
Tearing paper, slicing carrots, water changing to water vapor.
What is examples of Physical changes?
Properties that describes how matter changes into a new type of matter.
What are chemical properties?
A circuit that has more than one path along which a current can travel.
What is a parallel circuit?
A material that electric current can pass through easily.
What is a conductor?
When matter changes from a gas to a liquid.
What is the condensing phase?
A material that resists the flow of current but doesn't stop it.
What is a resistor?
Properties that can be observed using your senses.
What are physical properties?
A circuit that has only one path for current.
What is a series circuit?
A device that supplies energy to move charges through a circuit.
What is a electric cell?
When matter changes from a liquid o a gas.
What is the boiling phase?
A path which negative charges move.
What is circuit?
Particles that move fastest in gases
Which phase of matter moves fastest?
When electricity is caused by friction.
What is static electricity?
An arrangement of wire wrapped around a core, producing a temporary magnet.
What is a electromagnet?
When matter changes from a solid to an liquid.
What is the melting phase?
A material that current can't pass through easily.
What is a insulator?
When particles slow down and start to move slower.
What is when heat is moved away from particles of matter?
1) A source of electricity
2) A path
3)A switch
4) An object that uses electricity
What are the four parts to a circuit?
The space around an object in which electric forces occur.
What is an electric field?
The slowest moving mater particle.
What is a solid?
Current electricity is produced when negative charges move along a path.
What is how current electricity is produced?
