Study of world’s atmosphere

Question 17

Matter

Answer 17

anything that has mass and takes up space

Question 18

physical properties

Answer 18

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

Question 19

chemical properties

Answer 19

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

Question 20

States of matter

Answer 20

solid, liquid, gas, plasma

Question 21

Element

Answer 21

a substance that cannot be broken down into other substances

Question 22

most common elements within the crust of the earth

Answer 22

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

Question 23

Most abundant elements in Earth’s Atomosphere

Answer 23

nitrogen (.78), Oxygen (.20)

Question 24

Chemical vs Physical change of matter

Answer 24

Chemical - exchanges electrons, a new substance is formed.

Physical - merely a change in appearance

Question 25

The Law of Conservation of Energy states that -

Answer 25

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.

Question 26

Kinetic Energy

Answer 26

• Kinetic Energy exists whenever an object which has mass is in motion with some velocity. Everything you see moving about has kinetic energy.

Question 27

Potential Energy -

Answer 27

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.

Question 28

heat

Answer 28

the kinetic energy of random molecular motion (measure quantity)

Question 29

Temperature

Answer 29

– the measure of the degree of hot or coldness of an object

Question 30

Conduction

Answer 30

One object touching another

Question 31

Convection

Answer 31

fluids (or gases) transfer by the circulation
