=Assignment #10:= __What is the molecule made of?__ The molecule is made primarily of carbon, hydrogen, nitrogen, and oxygen. Some other elements are included but are much less common.

__What is/are the function(s) of the molecule? (What do they do in the body?)__ Biomolecules help digest microorganisms - making feces of all living things.

__What are 2 examples of the biomolecule group?__ Carbohydrates - starches and sugars Proteins - albumin and titin, also hemoglobin Lipids - Steroids and fats like glycerol Nucleic acids - DNA and RNA = = =Assignment #5:= __What is done to clean up oil spills and minimize their destructive effects on the environment?__ To clean up oil spills and minimize their destructive effects on the environment there are many things that can be done. One thing workers can do is place a boom around the tanker that is spilling oil. A boom is essentially a device that collects oil off the water by absorbing any oil that flows around it. Another thing workers can do to clean up oil spills is use skimmers. Skimmers are boats that will remove oil from the water. Another thing that can be done is planes can fly over the spill and drop chemicals that will break down the oil.

-__Define Solubility and Rate of Dissolution__ Solubility - The quality or condition of being soluble./The amount of a substance that can be dissolved in a given amount of solvent. Rate of Dissolution - the rate of how fast/slow something goes into a solution

-__Explain how temperature, stirring, and surface area affect each concept.__ Solubility - Temp - it depends on the materials. If the solution process **absorbs** energy, then i**ncreasing** the temperature i**ncreases** solubility, and vice versa. Stirring - does not affect solubility - it might make it go faster but it does not affect it. Surface area - solubility would go up because more of it can be going at the same time. Rate of Dissolution - Temp - increases because the molecules are moving faster. Stirring - increases the rate of dissolution because you are causing the molecules to move faster. Surface area - increases rate of dissolution because there are more particles for the solvent to work with.

Citations: [] [] = = =Assignment #4:= Atomic Structure - Unique - The way the hydrogen atoms attach to the oygen atom is unique. It causes one side of the molecule to have a negative charge while the other side has a positive charge. Definition - The arrangement of the parts of an atom, which consists of a massive, positively charged nucleus surrounded by a cloud of electrons arranged in orbits describable in terms of quantum mechanics.

Specific Heat - High - Having a high specific heat means that it takes a lot of energy to heat up water. Which also means that is takes longer for water to release that energy and cool down. Def - Specific heat is the amount of energy required to change the temperature of a substance.

Surface Tension - High - Water is adhesive and elastic. Having a high surface tension allows it to form as droplets instead of spread out as a film. Def - Tension of a **liquid**'s surface. Due to the forces of attraction between **molecules**.

Conducts Heat - Easier than any liquid exept Mercury - This Allows large bodies of water such as lakes to have a near uniform temperature. Def - Conduction - Conduction consists of **energy** transfer directly from **atom** to atom and represents the flow of energy along a **temperature** gradient.

Melting/Freezing Point - 32 degrees Fahrenheit or 0 degrees Celcius. Def - Freezing point - The temperature at which a liquid turns into a solid. Def - Melting Point - Vice Versa

Assignment #2: 1. One day i was going to burn a hole through my bass drum head. This gives your bass drum a flatter sound and a bit more of a punch. In order to burn the hole in the drum head you need a can without a top on it and your stove. First you need to heat up the edges of the can which has no top on it. Then when the can is hot enough place the can on the drum head and it instantly burns a hole through the drum head. I decided to try this. I found an old can of stain that would work great for it. I asked my dad if it would be alright to use it and he approved. he told me i didn't need to take the top off and that it would be fine. I was not so sure of this but decided to go through with it anyway. After about a minute of heating it, the top burst off letting out a loud bang! I was totally caught off guard by this and was scared half to death. My dad laughed at me for quite some time and eventually I did too. What happened was as I heated up the can, the air inside got excited which created more and more pressure inside the can. It got to the point where the pressure in the can did not equal the pressure in the air around it, causing the top to burst off.

2. code format="html4strict"     code Link: In this video a can is heated up with a slight amount of water in it, turning it into steam. When submerged in a cold container of water, the steam condenses and creates a pressure vacuum. Since the can is on the bottom of the icecream container it sticks too it and the container (approx 1kg) is able to be lifted from the pressure alone.

3. code format="html4strict"     code Link: [] In this video the man puts a candle in a bucket of water (with food coloring in it). Then he takes a beaker and puts it over the candle and into the water. This causes the candle to go out. When the candle goes out, the air inside the beaker is less excited. This means that the pressure in the beaker goes down. Because the pressure in the beaker goes down, the pressure in the air around it in not equal. For it to balance out, the water moves up in the beaker; elevating the candle.
