Blog Week 10

On Monday, we asked the question "Can the temperature change without changing the state of matter?" We concluded yes, if you don't heat or freeze them too much. Otherwise the movement and space will increase. We also asked the question "What are some factors that we could measure that might have an affect on the motion of its particles?" We said temperature, viscosity, volume and mass. From there we asked ourselves if we had a bucket or container with 500ML of ice water, would a 10 ML of 50°C or a 100 ML of 25°C would change the temperature the most? We debated on it for awhile. I told my group the 10 ML of 50° C wouldn't change the temperature at all and they said it would. I then said that the 100 ML of 25° C would change because even though there was more water it was colder so the molecules would not move that fast and there were more molecules to spread out and change the temperature. When we tried this experiment we figured out that more warm water has more of an effect than less hot water. On Tuesday, we went over our results from Monday's experiment every group had the same conclusion and results. We found out that energy is associated with the motion of (speed) particles. Also, that 100 ML make the temperature change because more particles were added and more quantity of heat. And we know temperature equals the number of particles not movement. We also know quantity equals heat and heat equals mass and speed. We then went on to ask ourselves "What is Energy?" We came up with kinetic, hydro, potential, solar, wind, chemical and nuclear. But we said that that energy is not like Baskin-Robbins, energy does not have 31 flavors, energy is just energy. Which means there is only one type of energy, but energy can be transferred and stored. Like MP3s can be stored on your Ipod, on a CD, in an e-mail and in a text; they are all the same, just stored differently. We also know now that heat is not energy it's a way of transferring. On, Wednesday, we did read "Energy and Kinetic Molecular Theory." From the reading we learned that energy maintains its identity after being transferred, energy can be viewed as a substance like quantity that can be stored in a physical system, and energy can flow or be transferred from one system to another. We also learned that that energy is stored but it's the same energy. We learned about thermal energy it stores more to energy to move faster, then phase energy stores more energy to stay away, then Chemical energy stores more energy to stay away and move faster, attractive force particles. We also found out the ways energy is transferred. They are working (W), heating (Q), and radiating (R). To find the change in energy the equation is working + heating + radiating, which is also known as W + Q + R. On Thursday we did an experiment of ice water to gas. We took the temperature every five seconds as the ice water was in a beaker on the hot plate. Finally at temperature 85.6° C the water was gone and it was after 2000 seconds of heating. Or experiment might not have been done accurate, because I expected the temperature to rise constantly instead it went up and down throughout the experiment, it never leveled out. On Friday, we did two worksheets. My group worked together on them, we knew some but others were really confusing and difficult. We hope that we will go over them in class.
