34. A block of aluminum has a volume of 17. 0 ml and a mass of 45. 9 g
A block of aluminum has a volume of 17.0 ml and a mass of 45.9 g. What is its density?

35. A block of aluminum has a volume of 17. 0 ml and a mass of 45. 9 g
A block of aluminum has a volume of 17.0 ml and a mass of 45.9 g. What is its density?
Answer= D= M/V
D= 45.9 g/ 17.0 ml
D= 2.7 g / ml

36. Using the graph above, describe how
temperature changes as the altitude in the
atmosphere increases.

37. Atmospheric temperature changes from
Using the graph above, describe how
temperature changes as the altitude in the
atmosphere increases.
Atmospheric temperature changes from
layer to layer. Gases expand when they are heated
and contract when they are cooled. Hot air is less dense
than cool air. Increasing air temperature decreases
atmospheric pressure. Decreasing air temperature increases atmospheric
pressure.
