What happens to a plant sealed in a container with gasoline fumes? You place four potted plants under inverted aquariums. Each aquarium also holds a bowl of gasoline. The trapped fumes surround the plant. Two plants sit at room temperature (24 degrees C). Two go into hot sun (34 degrees C). At each temperature, one plant gets three hours of exposure per day and the other gets six. You observe the plants daily for eight days. Plants exposed longer and at higher temperatures die faster. Six hours at 34 degrees C is the most damaging combination.
