If this relationship is direct, k = P/T. If it is inverse, k = P•T. Choose one of these formulas and calculate k for the pairs in your data table (divide or multiply the P and T values). Record the answers in the fourth column of the Data table. How constant were the values for k you obtained in Question 4? Good data may show some minor variation, but the values for k should be relatively constant. Comment on your calculated k values. Analysis Questions: What does temperature measure?
