In an experiment, a sealed container with a volume of 100 ml is filled with hydrogen gas. The container is heated to a variety of temperatures, and the pressure is measured. The data from the experiment is plotted in the figure.

Which of the following methods can be used to determine additional information regarding the gas? Select two answers.

(A) The slope can be used to calculate the number of atoms in the gas.

(B) The area under the graph can be used to calculate the work done by the gas.

(C) The vertical axis can be used to calculate the force the gas exerts on the container.

(D) The x-intercept can be used to estimate the value of absolute zero.
