1. The three types are Fahrenheit, Celsius, and Kelvin scales.
http://wiki.answers.com/Q/What_are_the_names_of_three_temperature_scales
2. The thermal energy is what causes the temperature to change because when the energy isn't very strong than it is cold outside but when it is strong it is hot outside because the molecule get heated up and energized from the thermal energy. The thermal energy is the energy of all of the particles in an object and you need to know the temp. of them and the heat to find this.
3. This basically means the amount of energy that is needed to make a substance get bigger by one degree Celcius. Such as water's specific heat is a lot higher than ice.
http://wiki.answers.com/Q/Why_does_water_have_a_high_and_specific_heat_capacity
4. It will melt in your hand because your hand is very warm compared to the ice which is frozen so since your hand is so warm you melt the ice. The ice doesn't make you colder it is just taking away the heat.
5. There are two things that have to do with why some things get hotter than others faster. One thing is just how much water (mositer) in the object. The other thing is some thinkings have higher or lower specific heat thing that I explained in problem 3. If it has a higher specific heat than it takes a lot longer than if it happened to have a lower one.

Objective 6:
1. This law shows how and why gases get bigger when they get hotter.
http://en.wikipedia.org/wiki/Charles%27_Law
2. As the temperature of a gas increases, the gas molecules move more crazily because they get more thermal energy.
3. The Robert brothers were the first to build one of these for Charels and then Charels flew in it first. http://en.wikipedia.org/wiki/Robert_brothers
4. When it landed local people attacked it. They wree afraid of it and so ripped it up with knives and other things.

5. The k is kept constant in the formula:

Objective 5:
1. This law shows the relationship between pressure and volume of a gas.
http://en.wikipedia.org/wiki/Boyle%27s_Law
2. As the balloon rises it begins to get bigger which means that they can't fill a balloon completely up or else it will pop.
http://wiki.answers.com/Q/Why_do_most_helium_filled_balloons_burst_as_they_ascend_to_high_altitudes
3. PV = k is the formula. P=pressure V=volume of gas k=constant value of pressure and volume
http://wiki.answers.com/Q/What_is_the_formula_of_Boyle's_law&alreadyAsked=1&rtitle=What_is_the_formula_for_Boyle%27s_Law
4. They use it when they do oxegen tanks because when they find the pressure in the tank they can see how much is actually left in the tank.
5. Scuba divers use it for their oxegen tanks because just like doctors they can see how much oxegen they have left.

5. Scuba divers use it for their oxegen tanks because just like doctors they can see how much oxegen they have left.
Objective 4:
1. The warmer particles are bouncing around everywhere because of the energy that the sun is giving out. This makes them warmer because they have more energy. The cooler particals don't have as much sun energy causing them to be less bouncy and wild so they get cold.
2. Ice-cream starts to melt on warm summer days because when it is cold for them feezer the paritcals are just sort of sitting there and not moving around as much but then the sun causes the particals to get energized so they start to heat up causing the ice-cream to melt.
3. The melting point of particals has a lot to do with the vibration of the particals. This is because as the particals begin to move around a lot they get a lot hotter causing the object to melt.
4. This happens when it is really humid in the air and then all the sudden it gets cold. This then makes the air dissolve so then the water is made into little drops of water like on a hot day and you see condensation on the cup.
http://wiki.answers.com/Q/Why_does_condensation_occur
5. Sublimation happens when a gas turns to a solid without becoming a liquid. From the website that follows I got this quote thing explaing it. "It is shown that the form of the sublimation process in which phase transformation takes place not from the geometric surface but in a certain layer of finite thickness is a stable one."

Objective 3:
1. There are six types of forms of energy related to they changes in matter. They are kinetic, potential, electromagnetic, chemical, electical, and last but not least thermal energy.
2. Kinetic energy
3. Potential energy
4. Electromagnetic energy is basically things like radiation waves, gamma rays, and other things like that, that we can't see.
5. That energy is electical energy. One example of this is the projector shoots these electrons out to form a picture on the board.

Objective 2:
1. Well a chemical and physical change are very different. A chemical change is when something that is inside of something else changes like the particles or mineral things that are in it change. A physical change is something that you can see. It is like if I died my hair green, you can see the difference on the external or the outside of me. http://wiki.answers.com/Q/The_main_difference_between_a_physical_and_a_chemical_change_is&alreadyAsked=1&rtitle=What_is_the_main_difference_between_a_physical_change_and_a_chemical_change
2. A chemical change can occor in four ways. One ways is that a solid is made. Another is that an object changes color. The third way is that gases are formed and made. The last way is that light, sound, and/or heat are made.
http://wiki.answers.com/Q/Four_ways_you_can_tell_a_chemical_change_has_taken_place
3. The law basically said that in a closed object that the mass of that object will stay the same. It was made by ancient Greek philosophy people but one man's name that helped a lot was Epicurus.
http://en.wikipedia.org/wiki/Conservation_of_mass
4. Tempature and thermal energy are very different. Tempature is when how hot something is, is the average of kinetic energy. Themral energy is averaged with kinetic energy and all the other different types of energy.
http://wiki.answers.com/Q/How_is_temperature_and_thermal_energy_different
5. Exothermic-A lizard is exothermic because it uses the sun to get body heat.
Endothermic-We are endothermic because we make our own body heat.

Objective One:
Objective 1:
1. Mass is more important for many reasons. One reason, which is the main one, is that if I were to weigh myself on Mars I would have a differet weight than I would on Earth. This shows that the weight of an object can change but the mass is always the same. Just like my mass wouldn't change even if I were on Mars. http://wiki.answers.com/Q/Why_is_mass_more_useful_than_weight_for_measuring_matter
2. the volume is 619.65cm3 (the three is supposed to be very small and on the top but I don't know how to do that)
3. The measurement of density is g/cm3 (same thing up there with the three being small and on the top)
4. D=mass over volume
5. V=L*W*H (* means times)
