(those guys are weird)

Homework 9: Bringing the Heat

Objective 1:
1. Fahrenheit, Celsius, and Kelvin

2. Thermal energy is the kinetic energy of the movement of the molecules and atoms in an object. A change in thermal energy can be detected by a change in temperature. This is heat as well because heat is a relative term that changes meaning as put into a situation.

3. Specific heat is the rate at which an object heats. If an object has a high specific heat, like water, then it takes longer to heat up than an object with a low specific heat.

4. Ice cubes melt in your hand because when heat is transfered it is always from hot to cold. So, the energy in your body which causes heat transfers to the ice cube which causes it to melt.

5. There are two major reasons that some things get hotter more quickly than others and they are both realated. The first is that some things have a lower specific heat than other objects. The second is that some things conduct heat better than others and some are just insulators so they wont conduct the heat or energy. The conduction level of an object is one of the factors that help us to get the specific heat.

Objective 2:
1. Thermometers measure temperature with mercury. Mercury "shrinks" when the temperature is lower and "grows" when the temperature is higher.

2. Kelvin and Celsius are very similar in that the difference in their boiling point and freezing point is 100, they are both metric, and Americans don't care to use them very frequently. :) Fahrenheit is fairly different from the other two and Kelvin and Celsius are completely different other than those few simple similarities. One way that Fahrenheit is different from the others is that Americans love this scale!

3. 5º C = 41º F

4. 860º F = 460º C

5. 209,000 J

Objective 3:
1. conduction, convection, and radiation

2. Heat flows from a warmer object to a cooler object.

3. conductors: allow heat / energy to flow through
    insulators: trap heat / energy

4. A copper pipe would work better as a conductor because it is metal and metal allows energy to flow through it.

5. I would build a tent because the fabric is an insulator which would keep the heat in and keep me warm.

Objective 4:
1. When matter heats up its particles have more energy. So, when the particles have more energy the object changes its state.

2. particles speed up in movement

3.

4. heat transfer/ Heat always goes from a warmer object to a cooler object so it gives the energy to the cooler object which then melts.

5. The skin of a potato is an insulator and is fairly water resistent so, if you don't poke holes in it there is a possibility of it exploding.

Homework 8: Gas Laws

This took some time but it was really interesting!


Objective 1:
1. I looked at an answer on answer.com (my inspiration) and it inspired me. Your weight may change depending on gravity and other factors, however your mass will stay the same. This is because you have the same numbers of atoms no matter the factors and your weight can change if you're on a different planet or go on a diet.
2. 619.65 cm to the 3
3. g/cm
4. M/V
5. LxWxH

Objective 2:
1. reversible/ unchangable and same thing/ new things (my inspiration)
2. color change, temperature change, smell change, and a solid is made (my inspiration)
3. The Law of Conservation of Mass states that mass in a closed system will always be constant no matter what forces are at work (my inspiration) the Law of Conservation of Mass was created by Antoine Lavoisier but Mikhail Lomonosov had similar ideas earlier (my inspiration)
4. temperature is the average kinetic energy in a substance while thermal energy is the total kinetic energy in a substance
5. elephant toothpaste (exothermic) Ansley and I doing an endothermic experiment (endothermic)

Objective 3:
1. kinetic, thermal, and electrical
2. kinetic energy
3. potential energy
4. Electromagnetic energy is the energy that is moving through wave lengths.
5. electrical energy, the electrical energy in the earth's atmosphere that is partially released as lightning in thunderstorms (my inspiration)

Objective 4:
1. Particals in energy move slower in cold temperatures and faster in warm temperatures.
2. When exposed to heat objects change their state, so ice cream melts.
3. The higher the temperature the more the particles vibrate. This causes stuff to melt because the more particles vibrate the hotter the object gets.
4. Condensation occurs when the air around a liquid is warmer than the liquid. This cause the gas around it to condense and become a liquid on the cup.
5. Sublimation occurs


Objective 5:
1. the relationship between pressure, temperature, and volume of a gas and its container
2. When the balloon is rising it is gradually expanding. So, if you filled the balloon completely it would have no room to expand causing it to pop.
3. PV = K (pressure x volume = constant)
4. Physicians must note the volume of a container for an inhaler or an oxygen tank so that the gas inside doesn't over expand.
5. Scuba divers also must note the amount of gas, the pressure which increses or decreases the speed of use, and know how much oxygen they have left.

Objective 6:
1. Charle's Law is an experimental gas law that talks bout how and why gases expand when heated. (my inspiration)
2. quickly
3. Charles
4. he had a succesful flight, but when he landed in Paris people through rocks in terror destroying the balloon.
5. pressure

baby elephant....and......Mr. Burke?

baby elephant sneezing......and......Mr. Burke?

ok guys you have to watch this. it's really funny and cute. also if you listen after the sneexe it sounds like Mr. Burke is there.......wierd.
