In a magical world, there is a room with walls that can change their opacity based on the temperature inside the room. The walls become completely transparent when it's warm and opaque when it is cold. On a particular day, Zephyr and Lakshmi decide to enter the room separately to play hide and seek. Zephyr, who is seeking, has a magical ability to change the temperature in the room at will. Lakshmi, who is hiding, can choose any spot in the room to hide. If Zephyr wants to catch a glimpse of where Lakshmi is hiding, what should Zephyr do with the room's temperature? Assume there is no other light source or way to see into or out of the room aside from the wall's opacity changes. Respond very briefly.
Zephyr would want to make the room warm in order to catch a glimpse of where Lakshmi is hiding. Since the room's walls become transparent with warmth, by increasing the temperature, Zephyr will turn the walls clear, allowing them to see inside the room. Since there are no other light sources or means of seeing into the room except for the opacity of the walls, Zephyr's best strategy is to raise the temperature sufficiently so that the transparency of the walls reveals Lakshmi's hiding spot. Once the walls are transparent and Lakshmi is visible, Zephyr can use their spatial reasoning to locate her hiding spot in relation to the surroundings which have now become visible through the transparent walls.
