UPC A4 Video Clip 1: Video group discusses Explanation #3 Part A UPC A4 Video Clip 1: Video group discusses Explanation #3 Part A The video group discusses why the number of gas particles decreased as the container (air only) was heated. UPC A4 Video Clip 2: A group's white board presentation of Explanation #1 Part A UPC A4 Video Clip 2: A group's white board presentation of Explanation #1 Part A A group in class presents its description and nano energy diagram for what happens to the particles of the propellant when the can is heated. They include both thermal and kinetic energy in their diagram, and the instructor explains why the thermal energy term should not be there. UPC A4 Video Clip 3: A group's white board presentation of Explanation #1 Part B UPC A4 Video Clip 3: A group's white board presentation of Explanation #1 Part B A group shows the nano table for Explanation #1 Part B. They have one error in the table and a student in the class questions it. The instructor agrees with the student's correction. UPC A4 Video Clip 4: A group's white board presentation of Explanation #1 Part C UPC A4 Video Clip 4: A group's white board presentation of Explanation #1 Part C A group explains why the container explodes when it is heated. They talk in terms of particles inside the container trying to move from high to low pressure. UPC A4 Video Clip 5: A group's white board presentation of Explanation #2 Part A UPC A4 Video Clip 5: A group's white board presentation of Explanation #2 Part A A group presents its macro-nano table to show why the air pressure in a tire remains constant as air is added and the volume increases. UPC A4 Video Clip 6: A group's white board presentation of Explanation#2 Part B UPC A4 Video Clip 6: A group's white board presentation of Explanation#2 Part B A group explains why the air pressure in a tire remains constant as air is added and the volume increases. UPC A4 Video Clip 7: A group's white board presentation of Explanation #2 Part D UPC A4 Video Clip 7: A group's white board presentation of Explanation #2 Part D A group explains why the air pressure in a tire increases when air is added and the volume remains constant. UPC A4 Video Clip 8: Video group uses whiteboard to present Explanation #3 Part A UPC A4 Video Clip 8: Video group uses whiteboard to present Explanation #3 Part A The video group begins by explaining why the number of gas particles in the can decreased as the container was heated. They are essentially saying that there was a movement from inside the can to outside the can because the gas moves from a region of high pressure to one of low pressure. Then, on their own, they constructed a macro-nano table to justify why the pressure stayed the same. Because the container was open, this was a challenging table to construct, and the group was unsure about some entries. The instructor offers some help. UPC A4 Video Clip 9: A group's white board presentation of Explanation #3 Part B UPC A4 Video Clip 9: A group's white board presentation of Explanation #3 Part B A group explains why it was important to invert the can in cold water. UPC A4 Video Clip 10: A group's white board presentation of Explanation #3 Part C UPC A4 Video Clip 10: A group's white board presentation of Explanation #3 Part C A group uses the macro-nano table to justify why the pressure decreases when the hot can is inverted in the cold water. UPC A4 Video Clip 11: A group's white board presentation of Explanation #3 Part D UPC A4 Video Clip 11: A group's white board presentation of Explanation #3 Part D A group explains in words why the pressure decreases when the hot can is inverted in the cold water. UPC A4 Video Clip 12: A group's white board presentation of Explanation#3 Part E UPC A4 Video Clip 12: A group's white board presentation of Explanation#3 Part E A group shares its energy diagram describing, in terms of energy, what happens when the hot can is placed in the cold water.
