Refer to Table 3.2 in the lecture and take the data for air, water (steam), and four other gases listed in the table. Plot the data in a graph with the thermal conductivity on the vertical axis and the temperature range from 200 K to 600 K on the horizontal axis. Use colors or different dashed lines to make the graph presentable and understandable. The graph should look like the graph in Figure 3.1 in the lecture. Provide a short explanation of the graph in three to five sentences.

Refer to Table 3.2 in the lecture and take the data for air, water (steam), and four other gases listed in the table. Plot the data in a graph with the thermal conductivity on the vertical axis and the temperature range from 200 K to 600 K on the horizontal axis. Use colors or different dashed lines to make the graph presentable and understandable. The graph should look like the graph in Figure 3.1 in the lecture. Provide a short explanation of the graph in three to five sentences.
