Mass is a measure of the quantity of matter in an object
Massage world measured in kilograms or grams
Matter is anything that is found within our environment
STATES OF MATTER
Solid state
a solar solutions does not flow and return it is definitive and the size
Liquid state
Liquid substance flow is Roberta still retaining the your volume.
Liquid take the shape of the container holding it
Gaseous state
Gaseous substance has no specific shape or size
there is no floor and expanding indefinitely to occupy the space in which they are held
CHANGE OF STATE IN MATTER
Matter change it is state from one form to another.
√gas can be changed to liquid through condensation process
√Liquid can be changed to solid through freezing process
√liquids can be changed to gas through evaporation process
√Gas can be change direct to solid through the deposition process
√solid can be changed direct to gas through sublimation process
Importance of changes of state of matter
- Changing of liquid to vapour used in refrigeration
- changes of state from solid to liquid and back to solve the state's make metallurgy possible
- Changes of state from Liquid water to steam make steam engine to operate
- Material will dry if the liquid it contains changes to vapour.
- Changes of state of matter very useful in water cycle.
Physical and chemical changes
Physical changes
Physical changes this is the change which affect a physical properties of a substance
In physical change on the physical properties affected but chemical properties does not affected, for examples, burning of candle
Chemical change
Chemical changes changes affecting chemical properties of the substance.
In chemical change the chemical property of substance affected for example rusting of iron burning of paper.
