Data Visualization

In order to rank the five ionic compounds according to the temperature change in 5 mL of water, we will use an online data analysis platform called CODAP. Below, you will see a CODAP workbench. CODAP will allow us to visualize our data immediately upon entering it into the platform.

Let's begin with familiarizing ourselves with the CODAP environment:

  1. The platform is below these instructions. Notice an example ionic compound (NaCl) has been entered for you. Enter your data for the five ionic compounds you tested below this example.
  2. To better visualize the data, we can make a graph. In order to create a graph, drag the Ionic Compound variable to the x-axis of the plot as shown in the GIF on the right.
  3. Drag the ∆T/gram variable to the y-axis of the plot as shown in the GIF on the right.
  4. Observe the resulting plot. Then answer the questions below the CODAP workbench.

These questions were answered in the previous steps. They are provided here for your reference.

Record all data from Investigation Part 1 in the data table below. 

Questions

Please answer the questions below.

Rank the five ionic compounds according to the temperature change in 5 mL of water from greatest to least in the table below by expressing the value as ∆T/gram.

Predict how your ionic compound rankings will look if we convert all temperature change data from ∆T/gram to ∆T/mole.
