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