The air in each of four syringes is slowly compressed so that the temperature of the air stays constant. The volumes before and after compression for each syringe are given in the table. The air in all four syringes is initially at the same pressure. Which syringe shows the smallest pressure change? volume before compression / cm³: 50, volume after compression / cm³: 10 volume before compression / cm³: 100, volume after compression / cm³: 50 volume before compression / cm³: 400, volume after compression / cm³: 25 volume before compression / cm³: 400, volume after compression / cm³: 100
