Explanation:

The hot water kills the leaf. When you put iodine on the leaves, it will turn reddish-brown. Iodine is an indicator that turns blue-black in the presence of starch. If the leaf was kept in the light it turns blue-black, which demonstrates that the leaf has been performing photosynthesis and producing starch.
