MODULE 1: Matter and It's Various forms
Lesson 2: Change in States of Matter
In this lesson I've learned that the phases of matter can change their phase from one to another.
The states of matter can be affected by temperature. One example is heat. When ice is exposed to heat the it will melt into a liquid. That process is called melting
Lesson 5.1: Elements
The elements in the periodic table are classified as metals, non-metals, and metalloids
Nonmetals - The elements of this are brittle,and they do NOT conduct electricity
Metalloids - Their physical and chemical properties fall in BETWEEN the nonmetal and metals group in the periodic table of elements.
Metals - these are shiny,malleable and ductile and they are good conductors of heat
This is the smallest particles of an element
Monatomic atoms - these exist as a individual atom/s
Are 2 or more atoms that are chemically combined
Diatomic Molecules - formed by a combination of 2 atoms
Polyatomic atoms - these contain 3 or more atoms
I've discovered that in our periodic table there are almost 118 different kinds of elements, and most of them are natural and the smaller percentage is man made
Lesson 4: Measuring Physical Quantities
Graduated Cylinder - this is used to measure a liquid but the volume of it should be read at the lowest of the menicus at our eye level
Triple Beam Balance - is use to measure the mass of an object
Thermometer - Is used to measure the temperature of a person or a object
Lesson 5.2: Compounds
A common example is water H2O, because there are 2 hydrogen atoms and one oxygen atom to create water
A compound is a pure substance that is made up of two or more elements chemically combined. This could be also made up of molecules or ions
Decomposition of Compounds
Thermal decomposition - This a process wherein a compound is being heated strongly
Electrolysis - This a process wherein electricity is being used to breakdown compounds
Ions - this are particles that are electrically charged , they carry positive and negative charges
Physical Quantities - This refers to the precise or needed measurement,volume,mass and ect.
Lesson 3: Separation and Purification
Pure substance - elements and compounds are the two kind of pure substances.
In this lesson I also discovered the different kinds of process that could take place in the 3 phases of matter
Distillation - Is the process of separating a pure liquid from a solution like separating of alcohol
Filtration - is the process of separating the solid particles, An example of filtration are Automotive Filter, Water Filter ect.
Evaporation to dryness - the process to obtain soluble solid from a solution by using heat to heat up the solution untill all the liquid evaporates
Chromatography - This is the method when you separate 2 or more components that dissolves the same solvent
Mixture - This are made up of combined substances that can be separated by a physical method.
Lesson 5: Classification of Matter
Pure Substance - is a form of matter that has a distinct property and has a definite (constant) composition
Mixture - is a combination of 2 or more substances, which they retain their distinct identities
Example: Sodium Chloride (NaCh1) and all compounds in the periodic table are pure substance
Example: Shampoo, soap, baby food
Lesson 5.3: Mixtures
Mixtures - these are made up of 2 or more substances that are physically combined, this could also be made up of elements or compounds.
Types of Mixtures:
Colloid - This is a heterogenous mixture that has a particle size that are intermediate in size. Unlike suspension, colloids cannot settle upon standing
Suspension - this is a heterogenous mixture wherein the particles here do not dissolve ina solvent and it remains settled upon standing.
Solution - This is a homogenous mixture wherein the solute dissolves in the solvent
Tyndall effect - this is the scattering of lights in any direction
suspension and colloids - exhibit this effect
Solution - does not exhibit this effect
Lesson 1: States of Matter
3 properties of Matter
Solid - Has a fixed volume and shape, and this cannot be compressed
Liquid - This has a fixed volume but doesn't have a fixed shape, but unlike the solid particles this could be compressed
Gas - Unlike solid and liquid this particle does not have a fixed shape nor volume. But like the liquid particle this can be compressed
