the following graph shows how density, temperature, and salinity of seawater are interrelated.
the following table contains data for five samples of water. these samples were taken at the same location in the atlantic ocean, but at various depths. use the graph to complete the table

these are the values of density that complete the table

Sample       density

A                  1024
B                  1027
C                  1026
D                  1025
E                  1028

Procedure: take the values of temperature and salinity for each sample given in the table, and enter the graph to read the corresponding density value.

1) Sample A: temp = 21°C, salinity = 34%

Locate the value 34 on the horizontal axis (salinity axis), move vertically upward until reaching the level of 21 for the vertical axis, read the value of the density on the curve that passes through the point (34, 21). That value is
density = 1024 g/cm^3.

That is the value to copy on the table.

2) Sample B: temp = 11°C, salinity =35 %

Locate the value 35 on the horizontal axis (salinity axis), move vertically upward until reaching the level of 11 for the vertical axis, read the value of the density on the curve that passes through the point (35, 11). That value is
density = 1027 g/cm^3.

That is the value to copy on the table.

3) Sample C: temp = 12°C, salinity = 34%

Locate the value 34 on the horizontal axis (salinity axis), move vertically upward until reaching the level of 12 for the vertical axis, read the value of the density on the curve that passes through the point (34, 12). That value is
density = 1026 g/cm^3.

That is the value to copy on the table.

4) Sample D: temp = 19°C, salinity = 35%

Locate the value 35 on the horizontal axis (salinity axis), move vertically upward until reaching the level of 19 for the vertical axis, read the value of the density on the curve that passes through the point (35, 19). That value is
density = 1025 g/cm^3.

That is the value to copy on the table.

5) Sample E: temp = 3°C, salinity = 35%

Locate the value 35 on the horizontal axis (salinity axis), move vertically upward until reaching the level of 3 for the vertical axis, read the value of the density on the curve that passes through the point (35, 3). That value is
density = 1028 g/cm^3.

That is the value to copy on the table.

D)can be increased in a closed system
