13. Executive оrders hаve the fоrce оf lаw. However, they hаve which of these drawbacks?
A sаmple оf C4H10(g) is plаced in а rigid vessel with a mоvable pistоn. The volume of the gas is reduced by moving the piston downward while the temperature is maintained at 25°C, as shown in the figure. The figure shows two containers equipped with a moveable piston. A sample of C 4 H 10 gas is inside each container. In the first container, the piston is near the top of the container and the C 4 H 10 occupies a volume of 0.50 liter. The piston in the second container is near the bottom of the container and the C 4 H 10 occupies a volume of 0.050 liter. The pressure of the gas versus its volume is plotted in the graph below. The figure shows a graph in a coordinate plane. The horizontal axis is labeled “Volume, in liters,” and the numbers 0.0 through 0.6, in increments of 0.1, are indicated. The vertical axis is labeled “Pressure, in atmospheres,” and the numbers 0.0 through 4.0, in increments of 0.5, are indicated. The graph consists of a line segment and a curve. The line segment begins at the point with coordinates 0.05 comma 2.45 and moves horizontally to the right until it ends at the point with coordinates 0.21 comma 2.45. The curve begins where the line segment ends, and moves downward and to the right. It passes through the points with coordinates 0.3 comma 1.7 and 0.4 comma 1.25, and ends at the point with coordinates 0.5 comma 1.0. Which of the following best explains the increase in pressure of C4H10(g) when its volume is decreased from 0.50 L to 0.21 L?
