Learning About: The Ideal Gas Law

Using your notes, answer the following questions.

  1. What is the formula for the ideal gas law? ______
  1. In the equation you wrote above, label each variable. For example: P = pressure.
  1. Table 2 (to the right) has the numerical values of the gas constant, R. Which is the value of R we will be using? ______

To make the units cancel out correctly, we will need to only use certain units of volume, temperature and pressure. Based on the units associated with your R value…

  1. What units of volume will we be using? ______
  1. What units of pressure will we be using? ______
  1. What units of temperature will we be using? ______
