#5What happens to molecules as theyare heated?
#6
•Explain why there is more oxygen at sea levelthan at the top of a mountain. Is yourbreathing different at these locations?Explain.
#7
•Explain one major factor that is a result of theatmosphere's ability to trap heat.
#8
•What percentages of gases make up ouratmosphere?
#9
•Why did you not include water vapor in youranswer to question 8? Explain using the word“constant”.
#10
•A ninth grade class tried to find out if adding salt to water wouldchange the temperature at which the water boiled (its boilingpoint).
•They created the following hypothesis: If you decrease the amountof salt added to water, then the boiling point will decrease.
•The students took five beakers, placed 200 mL of water in each andlabeled them A, B, C, D, and E. Next, they dissolved 4 gram of salt inbeaker A, 3 grams in beaker B, 2 grams in beaker C, & 1 gram inbeaker D. No salt was added to beaker E. Each beaker was placedover a flame and the temperature at which the water boiled wasrecorded.
•Your task: CREATE A DATA TABLE AND A GRAPH TO REPRESENTTHESE RESULTS:
•A: 101°C B: 102°C C: 103°C D: 104°C E: 100°C
