What is properties???
Any traits that can be measured such as density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.
What is chemical and physical properties?
Physical properties
Definition
: properties that can be observed without changing the atoms of the substance and the substances identity
examples
melting point
boiling point
freezing point
Chemical properties
Definition
: properties that is found when a substance goes through a chemical reaction
examples
color change
produces smell
release of gasses
What is chemical and physical change?
physical change
definition
: when a substance changes it's form without changing it's properties
examples
melting: when an ice cube is left at room temperature
vaporization: when water gets boiled, it turn into water vapor
freezing: freezing water into an ice cube
chemical change
examples
paper burning
cooking steak
iron rusting
definition
': when a substance changes it's for by a chemical reaction causing chemical changes
what is the relation between chemical and physical properties and change?
properties
Both substances molecules change
change
The looks of the substance changes
physical
when the substance changes state of matter the looks of the substance changes
chemical
when a chemical reaction occurs to a substance, the looks of the substance changes according to the chemical reaction that occurred on the substance
Example of physical and chemical change
chemical
: Cooking steak: When the steak is cooked, the steak produces many signs of a chemical change such as: producing odor, color change, releases gas, produces smell, and many more. The cooked steak can't be changed back into the uncooked steak after it's cooked..
physical
: Melting an ice cube into water: when the ice cube changes its state of matter, there wasn't any new substances formed and the water can be frozen back into becoming an ice cube again.
