What would the drawing look like if the volume and temperature remained constant while you removed enough of the gas to decrease the pressure by a factor of 4?

If the volume and temperature remain constant, and the pressure is decreased by a factor of 4, the drawing would show a decrease in the number of gas particles in the container, with the remaining particles more spread out. The overall size of the particles would not change, but the spacing between them would increase significantly to account for the decrease in pressure. The drawing would show a larger distance between the gas particles compared to the original drawing.
