Matter Quiz 2 – Study Guide

Scientific Method

• List the steps of the scientific method in the space below.

1.   State problem or question

2.  Write hypothesis

3.  Experiment

4.  analyse data

5.  Draw conclusions

6.  Share findings

Variables

Using the statements below, identify the independent variable and dependent variable, and write an if…, then…. hypothesis.

Fertilizer may affect the growth of corn.

IV =  fertilizer

DV = growth of corn

Hypothesis : If you apply 25 grams of fertilizer to corn once a week, then the growth of the corn will increase by 15%.

Eating walnuts may affect the growth of your hair.

IV =  walnuts

DV = hair growth

Hypothesis : If you eat 10 walnuts each day for 30 days, then your hair will grow 5 cm in a month.

Metric Conversions

Metric Prefixes in order:

Kilo, Hecto, Deka (Basic Units: gram, meter, liter) deci, centi, milli

8.5 km = 8500 m                            47 mm = 4.7 cm

45.6 cm = .456 m                           20 dkm = 2000 dm

5 hL = 500 L                                     1000 g = 1 kg

Measuring Matter

 Method Definition MetricUnits Equipment Mass the amount of matter in an object grams triple beam balance Volume of a solid(Regular Shape) the amount of space an object takes upL * W * H cm3, mL ruler, meter tape Volume of a solid(Irregular Shape) the amount of space an object takes up*water displacement cm3, mL graduated cylinder Density the ratio of mass to volume in a substanceD=mass/volume g/mL or g/ cm3 triple beam balance, graduated cylinder, ruler

Properties and Changes of Matter

1.  What is matter?

Anything that has mass and takes up space

2.  Why is air matter?

Air is matter because it has mass and volume; able to be observed in a balloon, while breathing, etc.

3.  What is mass?

The amount of matter in an object

4.  What units would I measure mass in?

Mass should be expressed in grams (g)

Triple beam balance

6.  What is volume?

cm3 or liters (l)

7.  How do I measure the volume of a regular solid (box)?  What units?

Length X Width X Height; units would be cm3

8.  What units do I use to measure the volume of an irregular solid (marble)?

Milliliter (ml)

Liter (L)

10.  What is the correct order for the metric units?

Kilo, Hecto, Deka, deci, centi, milli

11.  Why is the metric system important?

It is based on the number ten, used around the world, and convenient/easy for scientists to share information.

12.  What are the differences between atoms and molecules?

 Atoms Molecules Smallest unit of matter; made of protons, neutrons, and electrons; has a nucleus surrounded by shells/orbits Made of 2 or more atoms; atoms can be the same or different

13.  Draw what the four states of matter look like.

14.  What are some examples of plasma?

The sun, flames, fluorescent lights

Plasma > gas

16.  Which state of matter has the lowest energy?

Solids

17.  Define the following phase changes of matter:

 CONDENSATION Gas à Liquid MELTING Solid à Liquid FREEZING Liquid à Solid EVAPORATION Liquid à Gas SUBLIMATION Solid àGas

18.  Describe the following parts of an atom:

 PROTON Large, positively charged, found in the nucleus, determined by the atomic number NEUTRON Large, no charge, found in the nucleus, determined by subtracting atomic number from the atomic mass ELECTRON Small, negative charge, found in the shells/orbits, determined by finding the number of protons

19.  Describe the following terms:

 Atomic Mass The sum of the Protons and Neutrons of an element Atomic Number The number of Protons found in an atom/element Chemical Symbol The abbreviation for elements on the periodic table; can be one – two letters

20.  Describe what is happening in the graph below at points A-E. A Matter is a solid; temperature is increasing B Temperature is constant; solid is melting C Matter is a liquid; temperature is increasing D Temperature is constant; liquid is evaporating E Matter is a gas; temperature is increasing

21.  What must be added to get from A to E?

Thermal (heat) energy to increase temperature and separate particles.

22.  Draw and label an atom (Bohr model) for the element Neon (Ne).
