Objective 5:

1.  They are mechanical and chemical.
http://wiki.answers.com/Q/What_are_the_two_parts_of_digestion&isLookUp=1
2.  Mechanical digestion is when you hve to do something to digest your food for yourself like chewing but chemical digestion is when a chemical called hydrochloric acid breaks down your food. http://wiki.answers.com/Q/What_is_the_difference_between_mechanical_digestion_and_chemical_digestion#ixzz16btmgJUm
3.  This means they can't do mechanical digestions so the chemical digestion has to work harder.

Objective 4:

1.  H+
http://wiki.answers.com/Q/What_ion_is_present_in_all_acidic_solutions
2.  The acids make hydrogen ions and the bases make hydroxide ions.
http://wiki.answers.com/Q/What_happens_when_acids_and_bases_dissolve_in_water
3.  It ends up breaking down into H+ NO3 which is an acid.
http://answers.yahoo.com/question/index?qid=20080108190009AA0Uied
4.  The pH tells you how much H+ ions that are inside of a certain acid or base.  If the pH is lower than 7 it is an acid and if it is higher it is a base.
(remembered this from the question on objective 3)
5.  The concentration of hydrogen is pretty high when the pH is low which means the pH of 3 has more hydrogen ions than the pH of 7.

Objective 3:

1.  They are if something tastes sour, if it reacts to metals or carbonates, if it turns blue litmus paper red, a pH lower than 7, and lastly if in a solution it produces hydrogen ions.
http://wiki.answers.com/Q/What_properties_distinguish_acids&alreadyAsked=1&rtitle=What_are_four_properties_of_acids&isLookUp=1
2.  They taste bitter, feel slippery, can be caustic, and turn red litmus paper blue.
http://wiki.answers.com/Q/What_are_the_properties_of_bases#ixzz16botVnjO
3.  If the paper turns red it must be an acid and if it turns it blue it must be a base.
4.  You can tell because if the food is sour it is a acid and if it is bitter it is a base.
5.  You need to wear gloves because the fertilizer will hurt your hands.  Also allows you not to wash your hans so often while doing gardening.

Objective 2:

1.  Concentration is the measurment of what amount of one thing is in another thing.  To figure this out you need to know how the solvent is compared to the solute.
http://en.wikipedia.org/wiki/Concentration
2.  Solubility is used to idenify substances because it is a characteristic property of matter.
http://wiki.answers.com/Q/Why_is_solubility_useful_in_identifying_substances#ixzz16bmbSKQR
3.  There are three types and those are tempature, pressure, and type of the solvent.
http://wiki.answers.com/Q/What_factors_affect_the_solubility_of_a_substance&isLookUp=1
4.  When the tempature is hot the solid will melt and if it is too cold it will freeze.
http://wiki.answers.com/Q/How_does_temperature_affect_the_solubility_of_a_solid
5.  It can help because of the object's characteristic property of matter.  This helps you know how easily something may be able to dissolve inside of that certain matter.

HW 10:

Objective 1: Understanding Solutions

1. What are the characteristics of solutions, colloids, and suspensions? Suspensions are a "homogeneous fluid" that has solid particals that are large.  Colloids disperse in a substance evenly and solutions have much smaller particals than either of the other two.
http://en.wikipedia.org/wiki/Solutions
http://en.wikipedia.org/wiki/Colloids
http://en.wikipedia.org/wiki/suspensions
2. What happens to the particles of a solute when a solution forms?  The particals from the solute go away and are a part of the solevent.
http://zellescienceblog.blogspot.com/
3. How do solutes affect the freezing point and boiling point of a solvent?  The boiling point of the solvent gets bigger when a solute is added because a solution has a bigger boiling point compared to a pure solvent. The freezing point gets lower also.
http://eigthscience.blogspot.com/
http://eigthscience.blogspot.com/
5. What effects do solutes have on a solvent’s freezing and boiling points?  A solute makes the boiling point bigger because a solution has a bigger boiling point compared to a pure solvent. It also makes the freezing point a lot lower.  The coligative property helps to understand the boiling point elevation.
http://en.wikipedia.org/wiki/Boiling-point_elevation4. Suppose you mix food coloring in water to make it blue. Have you made a solution or solution or a suspension? Explain.  You would make a solution because it is going throughout the water and dissolves.

Test 9:

1.  Thermal energy is the total energy of all of the particles in one object while temperature and heat is an thermal energy moving from a hotter object to a colder one like when I touch a rock that has been in the snow for two days I am passing heat to it.  Temperature is the measure of the warmness or the coldness of some object compared to a set value.
2.   Some things get hotter faster than others because their specific heat is a lot more or a lot less than another object.
3.   One type of heat transfer is conduction and this is when heat transfer is from one place to another without the movement of any matter.  These transfer thermal energy very well and are many types of silver and other things like that.  The reason why silver and those things are conductors are because they are cold to the touch.  They are this way because it is the way the particles are arranged.  Another type is convection and this is when movement of heat transfer is by movement.  These things don’t transfer thermal energy well at all which makes them good for keeping you warm.  That is why they aren’t cold to the touch like conductors.  Some examples are clothes, blankets, and wool socks because these things don’t transfer the thermal energy well.  The last type is radiation and that is the transfer of thermal energy by electromagnetic waves.  Some examples are radio waves, microwave waves, and other object like this.  As humans we can’t see these, we just see a small part of this which is the visible light section.
4.   You need to raise the temperature by 209,000J.
5.   A tent would trap the air you are in and make it warmer which would be conduction.  The fire would send out heat to make you warm so that would be radiation.  Both of these would help but a fire would help the most because you would get warmer right away while being in your tent wouldn’t help right away, it would take a long time.  That is why I would build a fire and not set up a tent.
