Blog Week 12

On Monday, we went over the hotness lab again, we all agreed that more warm water would change the temperature of the cold water more than a small amount hot water. we also learned that if you add more pressure, the volume decreases, which causes CO2 to become liquid. From there we learned that heat capacity is the energy required to change the temperature of a substance by one degree Celsius. Specific heat is the heat capacity for one gram of a substance. We then learned the equation for heat capacity. q=mc△T, m=mass, △T=temperature change, c=specific heat and q=energy. We also learned about phase diagram. We learned that the change in temperature and change in state if the pressure is the same. Temperature is the same then there's a change in temperature and change in state. We learned that liquid to vapor is called evaporating, vapor to liquid is condensing, solid to vapor is sublimating, and vapor to solid is depositing. We also learned that ice is less dense than water. We even learned what the triple point is, it's where ice liquid and vapor all exist. On Tuesday, we did some questions on the CQSP specific heat worksheet. For question one we got B because it was exactly like the hotness lab and more warm water was better than less hot water. On number two it said to explain why we choose what we choose and we said more particles are in the bigger amount of water so more energy needs to be transferred into B. More particles get energy than the A pot. On Wednesday, we finished that worksheet the front of the sheet was pretty simple we said for number four that the hood of the car will be hotter and for five we explained why we choose the answer for number four. We said the hood was hotter because metal transfers energy faster and more easily than water. Therefore, it was able to conduct energy better. Number six asked which would take more energy water or metal, we said water would require more heat energy to change the temperature. The back of the sheet was very difficult. We also did the specific heat worksheet, throughout the worksheet we used the equation q=mc△T. I understood this worksheet very well. My group had to present number six we took 95 minus 10 to get 85 which was △T and c equaled 4.186 and q= 210,000,000. So, the equation was 210,000,000=m(4.186)(85), from there we solved and we got 590,202.636 grams. For me the worksheet was easy and I think I understand the equation fully. On Thursday, we went over the worksheets in class and I found out I did everything right. We learned that Eth is thermal account, it's measures the motion of particles and their speed by the means of temperature. Eph is the arrangement of particles. These are not different energies they are just different ways of storing energy. We also learned that the melting stay is Eph, the heating stage is Eth which is where we also use the equation q=mc T, and boiling is Eph. On Friday we took and assessment. It was ok, but I had some difficulty with the assessment. I hope I did ok.
