Define Chemistry

The study of matter and the changes it undergoes

Define Inorganic Chemistry (3)

Inorganic- Chemistry of all that is not organic1. Study of the metals and non-metals and their reactions2. Things not derived from living things3.Things that do not contain carbon

Define Organic Chemistry (2)

Organic- Chemistry of Carbon and and carbon containing compounds. - Chemistry of those things derived from once living things.

Define Biochemistry (2)

What is used to measure Length?

Basic Unit- Meter1m=39.37in.1in=2.54cm

What is used to measure Volume?

Basic Unit- Liter1L=1.06 quarts1 fluid oz.=29.57ml =30ml1cc=1cm3=1ml

What is used to measure Mass and Weight?

Basic Unit- Kilogram1Kg=2.2lbsThe lab basic unit- Gram 1/1000kg1oz=28.35g=30g1lb=454g

Define Mass

A measure of the quantity of matter a body contains

Define Weight

A measure of the gravitational attraction of the earth for the body.

Define Heat (2)

Heat - the energy that causes there to be changes in matter (measured in calories)1. amount of heat necessary to raise the temperature of one gram of water 1degree C2. calories= # of grams of water X # degrees change in temperature

What is used to measure heat?

Temperature

What is used to measure temperature?

Celsius and Kelvin

Temperature is

the hotness or coldness o

Degree Celsius or Degree Centigrade

Used in most scientific study

Kelvin Scale

Used in many mathematical formulas of chemistry-0 K is absolute zero-an abstract number-when all things in the universe come to a halt

Conversion from Celsius to Kelvin(Absolute)

K= C +273

Conversion Kelvin (Absolute) to Celsius

C= K - 273

Chart of Required Temperatures

Define Energy

The ability or capacity to do work

Define Potential Energy

Stored Energy- Has the potential to do work

Examples of Potential Energy

-food-gasoline-coiled spring-battery

Define Kinetic Energy

The energy of motion

Examples of Kinetic Energy

-current of a river-wood-burning-motor running

Define Chemical Energy

Energy associated with chemical reactions

Define Exothermic Reaction

Absorbs heat (feels cool)

Define Exothermic Heat

Releases heat (feels hot)

The Law of Conservation of Energy

-Energy is neither created not destroyed in a chemical reaction-only changed in form

The Law if Conservation of Matter (Mass)

-Matter (Mass) is neither created nor destroyed in a chemical reaction

The Law of Conservation of Matter and Energy

- In any type if reaction, mass or energy can be neither created or destroyed; they can only be interconverted(change one to other).-nothing is lost in the reaction

A measure of the gravitational attraction of the earth for a body is

Weight

A measure of the quantity of matter that a body contains is

Mass

All things in the universe come to a halt when what is reached?

Absolute zero = 0 K

How is heat measured?

By temperature ( its hotness or coldness)

The amount of heat necessary to raise the temperature of one gram of water one degree Celsius is?

Measured in calories

The kilogram is the metric system basic unit of

Mass and Weight

The Liter is the metric basic unit of?

Volume

What do you add to the degrees C when converting to Kelvin?

273

What is the laboratory basic unit of weight measurement?
