Kevin activates an instant hot pack to put in each glove while he trains for the Iditarod dog sled race in Alaska. When the hot pack is exposed to air the iron in it reacts with oxygen to form iron (III) oxide. How could Kevin modify this device to make a longer lasting product?

I think it's D

Explanation:

because it says when ever air hits the iron it reacts so if we make a slower release then it will take less time to get cold !

have a great day because if you dont you and i will be sad
