Overview         (For age - group : 11 - 16 )

This educational science animation on extensive and intensive properties of matter also contains detailed explanation of physical and chemical changes; the animation takes up each property and explains it elaborately. It clears away the confusion as to why pressure is an extensive but not an intensive property.

Details of the animation/ movie /software

The animation contains a visual explanation of why certain properties are considered as intensive and some as extensive, with many examples. Also dealt in detail are Physical and chemical change. This educational animation will clarify all doubts about properties of matter.

Physical properties of matter can be divided into two parts - Intensive and extensive

Intensive properties do not depend on the amount of the matter present. They are color, odor, luster, malleability, ductility, conductivity, hardness and softness, density, pressure, boiling point and melting point.

Color: Perception of the different wavelengths of light.
Odor: Property of perception of the sense of smell.
Luster - Shininess of surface. Almost all Metals having shining surface
Malleability - The ability of a substance to be beaten into thin sheets.
Ductility - The ability of a substance to be drawn into thin wires.
Conductivity - The ability of a substance to allow the flow of energy or electricity. Metals like Copper, bronze, steel are good conductor of heat and electricity
Hardness and softness- how easily a substance is scratched.
E.g. diamond is the hardest substance known, iron and aluminum are hard while magnesium is a soft metal
Density is the mass of a substance divided by its volume
Pressure: Force per unit area. The standard unit for pressure is the Pascal (Newton per square meter).
Boiling Point - The temperature at which the vapor pressure of a liquid is equal to the pressure on the liquid (generally atmospheric pressure)
Melting point: - The temperature at which a solid becomes a liquid
Ice melts at 0 Deg C hence melting-point of ice is 0 Deg C

Extensive Properties are those that depend on the amount of matter present.
Mass, weight, volume and length are all extensive properties of matter
Mass - A measurement of the amount of matter present in an object.
Weight - A measurement of the gravitational force of attraction of the earth acting on an object. It is given by product of the mass of the object by the acceleration due to gravity W = m g. The SI unit is Newton (N) or kilogram-meters per second squared.
Volume - A measurement of the amount of space a substance occupies.
Volume is the space actually occupied by an object or the bulk of some substance.
Length is the linear extent in space from one end to the other. The SI unit of length is meter (m).

Physical change
A change that affects the size, shape or color of a substance but does not affect its composition.
Physical change is reversible and temporary.
Melting of wax is physical change

Chemical change
This type of change refers to a material changing to a completely different type of material or being transformed to a new substance. This process involves bond breaking and bond forming such that material changes its identity. E.g., wood burning is a chemical change.

Ans:
   
Q4: what is the relation between size and physical properties of matter? ananthan.r 16/3/2008
Ans: Size is related to volume, if the mass is increases as volume increases the density and buoyancy will generally vary little, but if volume increases with constant mass then density decreases increasing buoyancy, it also gives the load bearing capacity (determined by specific weight when density is multiplied by gravity).
   
Q5: compare elements, compounds and mixtures while considering these properties 1)composition 2) PHYSICAL PROPERTIES SUCH AS MELTING POINTS 3)SEPARATION. THANK YOU VERY MUCH. sareeta 4/3/2008
Ans: In case of both composition and physical properties, the criterion for separating element compound or mixtures into any of the three distinct types is very difficult, say in case color, odor, malleability, melting point, boiling point, density, mass, weight and volume, there are many overlaps for each criterion and you cannot distinctly categorize a substance into element, compound or mixture. In case of separation, mixtures are separable but elements and compounds are not.
   
Q6: What is volume? Jason 19/9/2007
Ans: The volume of a solid object is the three-dimensional concept of how much space it occupies, often quantified numerically. One-dimensional figures (such as lines) and two-dimensional shapes (such as squares) are assigned zero volume in the three-dimensional space. (Wikipedia)
   
Q7: WHY SIZE MATTER IN PHYSICAL AND CHEMICAL PROPERTIES OF MATTER KARTHI 30/3/2007
Ans: Size is related to volume and for a given mass; it determines how dense an object will be. This in turn is cross related to buoyancy (whether a ship will float or sink), calculating load bearing capacity (determined by specific weight when density is multiplied by gravity), in chemical properties larger sized compounds move much slower than the smaller ones (NH4 and HCL experiment), and are unstable (radioactivity and fission)
