Today in class our taecher, Mrs. Sorensen, came to each pod of desks and had a conversation about the silent labs and how they expressed each of the three preasure volume and temp. laws. our pod had to explain how the toy story balloon showed the Charale's law. It showed this law becuase there was a change in temp. due to heater, and a change in volume becuase the particals in the ballon started bouncing off eachother creating a bigger volume. but the preasure never changed. We also had to explain why the water bottle cannon showed the Boyle's law. this law was explained becuase when we crenckled up the bottle we decreased the volume. when we decreased the volume the particals had less room to move around. this caused the particals to bump into eachother and cuase a greater preasure. but the temp. never changed. along with talking about these labs ans laws we also were asighned preasure problems. they can be found on the teachers website.
