Matter of the day: Combustion


What is it?:

The reaction of hydro-carbons and oxygen make light, heat, CO2, H2O, and ash

Why does it matter? _____________________________________________________________

Vocabulary: (matter: anything stuff (has mass) that takes up space (volume).) (substance: a type of matter.*mass: how much matter there is.) atom-smallest matter with chemical properties sub-atomic particle: parts that make up an atom nucleus-the center of an atom *proton: positive particle of an atom

  • atomic number= number of protons

*neutron: no charge particle of an atom

  • atomic mass = protons + neutrons

electron cloud-area around the nucleus where electrons are *electron: negative particle of an atom: moves fast, can be found anywhere in the electron cloud element: one of over 100 types of atoms:

  • each classified by the number of protons
  • each reacts differently to form different substances

Essentials: 16.A pure substance is stuff made of only one kind of matter with definite properties.(i.e. sugar, salt, iron, & copper.) 17.Three states of matter are: Solid, Liquid, and Gas. Matter will change from one state to another if thermal energy is absorbed or released. (i.e. heat solid ice and itbecomes liquid water.) 18.Some pure substances, called elements, cannot be broken down into othersubstances by any chemical means. (i.e. iron, copper, gold, carbon, & chlorine.) 19.An atom is the smallest particle of a substance (matter.) 20.The nucleus in the center of the atom made of protons& neutrons. 21.Protons are tiny positively charged particles. 22.Electrons are tiny negatively charged particles that are found in orbit around thenucleus. 23.A molecule is a group of atoms that are joined together and act as a single unit.(i.e. a water molecule is made of 2 hydrogen atoms tied to 1 oxygen atom: H2O.) 24.Physical changes change the form of a substance, but not its identity. (i.e. ice issolid water, a crushed can is still a can.) 25.In chemical changes one or more substances combine or break apart to formnew substances. (i.e. burned wood becomes charcoal and carbon dioxide gas.) 26.Volume is the amount of space that matter occupies. (i.e. a 2-Liter bottle of soda) 27.A solid has a definite volume and a definite shape. (i.e. spilled rocks look the sameas in a glass.) 28.A liquid has no definite shape of its own, but has a definite volume. (i.e. watertakes the form of the bottle it’s in and spreads out when spilled.) 30.A Gas has no definite shape of its own and can change volume easily. (i.e. askunk’s spray on a dog fills a room quickly.) 31.The elements can be arranged by similarities in the Periodic Table of the Elements. Elements in the same column react similarly. Elements in the same rowhave similar electron levels.

Matter and changes Day 3

Matter of the day: Solution


What is it?:

Salt (NaCl) dissolves evenly throughout water. NaCl atoms split up in solutions, but get back together when the water evaporates away.

Solvents are different liquids that dissolve different types of substances.

Vitamins C and B are water soluble. Vitamins A,D,E,K are fat/oil soluble.

Why does it matter?

A solution is not a new substance!

Matter of the day: Compound

Formula:


What is it?: A molecule made from 2 or more different elements.

H2O and CO2 are compounds.

Why does it matter? It’s how we get a gazillion substances from 100+ elements..

Matter of the day: Napthalene Phases in a Flask


What is it?: A substance with low melting and vaporization points close to room temperature

Why does it matter? Crystals form quickly on the flask walls from the vapor and the liquid becomes slushy as it cools..

Essentials:1

1. Energy is the ability to do work or cause a change.  Examples are mechanical, thermal, chemical, electrical, electromagnetic, and nuclear.

2.Two kinds of energy are:

  1. Kinetic energy is the energy of motion. (i.e. a book falling)
  2. Potential energy is energy that is stored and ready to be released. (i.e. a book on a table ready to fall)

3.Temperature is a measure of the average kinetic energy of the individual particles (i.e. two units of temperature are degrees Fahrenheit (°F) and degrees Celsius (°C).

4.Thermal energy is the total energy of all of the particles in a system.

5.Heat is thermal energy moving from warmer objects to cooler objects.

6.Heat is transferred (moved) in three ways:

  1. Conduction – the process of heat being transferred from one particle of matter to another without the movement of matter itself. (i.e. by touch)
  2. Convection – the movement that transfers heat by the movement of currents within a fluid. (i.e. a fire’s heat rises & warms the air above, cool air falls)
  3. Radiation – the transfer of energy by the electromagnetic waves. (i.e. heat from a fire warms your hands and face from a distance)

7.Conductors are materials that conduct energy well. (i.e. metal pot handles, copper wire)

8.Insulators are materials that do not conduct energy well. (i.e. pot holders, plastic coating on wires)
