Chemical and physical propeties
There are properties that change his phisical aspect
Is the capacity to atraction the magnet or metals
Is the capacity of drive the thermal
Is the capacity of drive the electricity
Is the capacito of transferring light
Is when a outer force deform the object
The extensive propeties vary according to shape, mass and volum
The speciphic propeties are the propeties that do all the materials difenrent and ar spesiphic and unic for any material for exampel the melting frozen pint of the water are 0 º
Physical changes are when a material change of its physic for example when a cup it brakes this is a physical change or when wi apply a force into a paper and it changes this is a physical change.
Chemical changes are the ability of a material to transform in other substance, after doing a reaction like burning.
To identifi the chimical changes there are some characteristics that are the same to divide the chimical changes in groups.
FORMATION OF GASES: the cration of gases aperar when tow or more do a chimic reaction and formate gases
SMELL: the smell of the objects can change if some microrganisms
DIFFICULT TO REVERSE
Physical : in physical changes the proces can be completed one example is the water cycle
Chemical: in chemical the process it will be difficult to be completed because if you divide the components of a mixture these means that we have to return the components to the original components
COLOR: one of the things that change the color of the object is the oxidation
TEMPERATURE: the teperatur change when a material like wood it entry in contact with oxigen an ti do areaction
