Q

Meteorology

A

Study of world’s atmosphere

17
Q

Matter

A

anything that has mass and takes up space

18
Q

physical properties

A

Physical properties include color, smell, density, buoyancy, boiling, freezing and melting points. If you crumble a piece of paper it has not changed chemically.

19
Q

chemical properties

A

Chemical properties are when the matter forms another form of matter. The most common example of this is rusting.

20
Q

States of matter

A

solid, liquid, gas, plasma

21
Q

Element

A

a substance that cannot be broken down into other substances

22
Q

most common elements within the crust of the earth

A

Oxygen (.46), Silicon(.28), Aluminum(.08)

23
Q

Most abundant elements in Earth’s Atomosphere

A

nitrogen (.78), Oxygen (.20)

24
Q

Chemical vs Physical change of matter

A

Chemical - exchanges electrons, a new substance is formed.

Physical - merely a change in appearance

25
The Law of Conservation of Energy states that -
energy cannot be created or destroyed, but can change its form. The total quantity of matter and energy available in the universe is a fixed amount and never any more or less.
26
Kinetic Energy
- Kinetic Energy exists whenever an object which has mass is in motion with some velocity. Everything you see moving about has kinetic energy.
27
Potential Energy -
Potential energy is energy due to position or stored energy. Potential energy is also called gravitational potential energy. Pulling back a rubber band has potential energy until it is released.
28
heat
the kinetic energy of random molecular motion (measure quantity)
29
Temperature
– the measure of the degree of hot or coldness of an object
30
Conduction
One object touching another
31
Convection
fluids (or gases) transfer by the circulation
32
radiation
doesn't require medium
33
thermal energy
energy from heat
34
Boiling Points (C,K,F)
(100,373,212)
35
Freezing Points (C,K,F)
(0,273,32)
