Answer

1) Pressure increases due to more particle-wall collisions. ### 2) Pressure increases as particles collide more frequently in a smaller space. ### 3) Temperature and particle count are constant; pressure and volume are inversely related. Explanation 1. Explain why pressure increases with more particles Pressure rises because more particles collide with the container walls, increasing the frequency of collisions. 2. Explain what happens when container size decreases Decreasing the container size forces particles into a smaller space, increasing collision frequency and raising pressure. 3. State constant in Boyle's law and relation between pressure and volume Boyle's law assumes temperature and number of gas particles are constant. **Pressure and volume are inversely related**: P \propto \frac{1}{V} or P_1V_1 = P_2V_2.
