Final answer:
To communicate the data effectively, a scientist would develop a graph to visually represent the pressure changes.
Step-by-step explanation:
To communicate the data effectively, a scientist would (c) develop a graph to visually represent the pressure changes. Graphs are a powerful tool for visualizing data, allowing patterns and trends to be easily observed. By plotting pressure values on a graph, scientists can show how pressure changes with different variables such as temperature, volume, or amount of gas.
