Calculate the difference in pressure between the top and the bottom of a container exactly 84 cm deep filled at 27 ℃ with: Water (d = 0.990 g/cm3 )
Copper (d = 13.6 g/cm3 )

The reaction q+r2=r2q is found to be first order in r2 and

Put these processes of the water cycle in the correct order, starting at the point where the water is in the lake: 1. water evaporates into the atmosphere 2. rain, snow, or other precipitation falls 3. water collects into larger bodies of water 4. water vapor condenses into liquid water
