If students have difficulties differentiating the characteristics associated with covalent and ionic bonding, they will suffer with future topics and other branches of chemistry. In elastic collisions kinetic energy was always conserved. f. Make a hypothesis about which set of sample mass, the 200 g or 100 g, will heat up the In physics momentum is always conserved. These results are shown in the table below. kinetic energy to object 2. We traded experiments and materials with another group, so each group got a chance to watch an unbiased group perform their experiment. first example, heat energy is transferred from the stove to the pot of water, and the water absorbs the heat energy and will eventually begin to boil. If you added the amount of KE and heat energy together, you would get the original value for GPE because energy is conserved. Place the pH probe in the beaker and record the pH in the data table. In experimental situations the numbers will not come out to be exactly perfect, but if the ration of the momentums is close to one it will indicate that momentum has been conserved. Place the calorimeter (no lid) on the balance and tare the balance. This would force the carts to repel each other and not stick together during collision. When you are finished, submit this assignment to your teacher by the due date for full credit. The standard cart moved to a velocity of zero and was still. This will teach how to do momentum calculations for a variety of different situations where momentum is conserved - calculations that will illustrate the nature of momentum, and the fact that momentum is in fact conserved. Lesson: Types of Chemical Reactions, Project: Thermal Energy and Chemical Reactions Students apply knowledge of technological design, as well as techniques of project-based learning in order to investigate the relationship between chemical processes and the release of thermal energy.
