physical and chemical
Characteristics of matter that can be observed and measured without changing the identity of the substance
Ex: density, phase change, color, mass, malleability, ductility
The amount of mass matter has in a given space volume; mass per unit volume
Ex: Density can be calculated using the formula…
The ability of a substance to be squeezed into a smaller volume or space
Ex: gases, stress ball, and balloon
A characteristic that describes how a substance will interact with other substances during a chemical reaction.
Example - reactivity, flammability, emission of light, forming a precipitate
The ability for a substance to react rapidly with oxygen and releases energy in the form of light or heat.
Combustion
Occurs when a substance changes its appearance but not its identity or chemical composition
Ex: ice cream melting, cutting hair, puddle vaporizing
the physical forms of matter, which include solid, liquid, gas, and plasma
Ex: solid, liquid, gas, and plasma
the attraction of a substance to a magnetic field of iron, cobalt, and/or nickel
Ex: Iron, nickel, and cobalt are elements on the Periodic Table that are magnetic.
Substance is changed into a new substance with different properties
Example - sodium and chlorine combining to make salt, milk and vinegar forming a precipitate
Size-independent (intensive) property is that property that is not affected by the amount of matter.
Examples:
Density
Melting Point
Freezing Point
Solubility & Conductivity
the amount of space an object takes up
Ex: The rock in the picture above has a volume of 10mL
the physical forms of matter, which include solid, liquid, gas, and plasma
0℃/32℉
100℃/212℉
A liquid’s resistance to flow
x. hand soap slowly running down a bottle
Lava has a greater viscosity than water
is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products.
Example - Sodium and Chlorine react to form salt
Size dependent (extensive)property is that property that is affected by the amount of matter.
Examples:
Volume
Mass
Amount of matter in an object
Ex: Mass can be measured using a triple beam balance. In the picture above the mass of the object is 288 grams.
the ability of a substance to dissolve
Ex: sugar dissolving in tea
The ability of a substance to be drawn, pulled or shaped to produce a wire
Ex: Copper wires, cable wiring
How likely an element is to form bonds with other elements.
Group 1 metals are highly reactive elements.
A measure of the force of gravity on an object
Ex: Weight changes based on location. You would weigh less on the moon because gravity is weaker on smaller masses.
the ability of a substance to transmit thermal or electrical energy
Conductors are materials that allow heat and electricity to flow
The ability to pound or flatten into a thin sheet
Ex. making sheets of aluminum foil; coin press machines; rolling dough
is the ability of a chemical to burn or ignite, causing fire or combustion.
Rubbing alcohol is very flammable
