Vuestion 6 Vandile sprays some perfume in the corner of a small closed room. Linesri is standing in the middle of the room and Andrew is standing in the opposite corner. 6.1 Who will be able to smell the perfume first, Linesri or Andrew? 6.2 Will Andrew eventually be able to smell the perfume? Explain your answer. 6.3 Name the process by which the perfume parlicies move. 6.4 Is the process mentioned in 6.3 an active or a passive process?

**6.1 Who will be able to smell the perfume first, Linesri or Andrew?** **Answer:** *Linesri will be able to smell the perfume first.* **Explanation:** Linesri is positioned in the middle of the room, which is closer to the corner where Vandile sprayed the perfume. Due to the proximity, the concentration of perfume molecules near Linesri will be higher initially, allowing her to detect the scent before it disperses further to reach Andrew in the opposite corner. --- **6.2 Will Andrew eventually be able to smell the perfume? Explain your answer.** **Answer:** *Yes, Andrew will eventually be able to smell the perfume.* **Explanation:** Perfume molecules disperse throughout the room via the process of diffusion, which involves the movement of molecules from an area of higher concentration to an area of lower concentration. Over time, the concentration of perfume molecules will increase in all parts of the room, including the area where Andrew is standing. As the perfume spreads evenly, Andrew will reach the threshold concentration required to detect the scent. --- **6.3 Name the process by which the perfume particles move.** **Answer:** *The process is called **diffusion**.* --- **6.4 Is the process mentioned in 6.3 an active or a passive process?** **Answer:** *Diffusion is a **passive** process.* **Explanation:** Passive processes do not require external energy to occur. Diffusion relies on the natural kinetic energy of molecules to move from areas of higher concentration to areas of lower concentration until equilibrium is reached.
