Properties
Matter can be described by two properties
What is Physical and Chemical?
Antifreeze, oil, juice, gasoline are examples
What is a liquid?
When a solid transforms into a liquid, it is referred to as
What is melting?
Mr. Chan threw a banana peel in the garbage. The next day the peel turned brown
What is a chemical change?
All matter is made up of this
What are particles?
All matter have these two things in common
What is mass and volume?
This state can hold its own shape
What is a solid?
This is the only metal that can remain as a liquid at room temperature
What is mercury?
Substances that take part in a chemical change and the substances that are formed
What are reactants and products?
The more of this there is, the faster the particles move.
What is energy?
This is the mass of a material that occupies a certain volume
What is density?
This is state can be compressed
What is a gas?
The temperature at which a substance boils
What is the boiling point?
This can be separated into parts by physical changes
What is a mixture?
Particles are closely packed and held rigidly in place
What is a solid?
ml, cm3 are units for this particular property
This is a mixture of gases which include nitrogen, oxygen, water vapour and carbon dioxide
What is air?
When matter is transformed from one state to another, it is referred as
What is changes of state?
This cannot be separated or broken down by physical or chemical changes
What is an element?
Particles in gases do this
What is move freely in straight lines?
This substance has the same proportion of mass to volume
What is water?
This state exists in the most matter in the universe.
What is plasma?
This is the measure of the average kinetic energy in particles.
What is temperature?
The total mass of the products is the same as the total mass of the reactants
What is the law of conservation of mass?
A scientific explanation of the behavior of matter based on all matter being made of particles that possess kinetic energy
What is the Kinetic Molecular Theory?
