What happens when I hold a wet cardboard over a Bunsen burner flame vertically and horizontally?

Answer 1

Because the position of the cardboard is vertical it obviously displays the intensities of theheat. The bottom of the cardboard displays the hottest part of the flame where the char is firstseen. While the top area of the cardboard took time to dry up and char because is cooler in thisarea that those at the bottom.

Answer 2

When held vertically, the cardboard will likely catch fire and burn due to the heat from the Bunsen burner flame. When held horizontally, the wet cardboard may char and smoke but may not ignite fully due to the moisture content. However, the heat may cause the water in the cardboard to evaporate, creating steam and potentially causing the cardboard to warp or bend.
