heat was blank to the gel immediately when placed on the hand which one added or removed

Answer 1

It seems like you are asking about a heat transfer situation involving a gel applied to a hand. If the gel feels cold when applied to the skin, it means that heat is being removed from the skin to the gel. In contrast, if the gel feels hot, it means that heat is being added to the gel from the skin.

So, if "heat was blank to the gel immediately when placed on the hand," the appropriate word to fill in the blank would depend on the sensation:

• If the gel felt cold: "removed"
• If the gel felt hot: "added"

Please provide more context if you have a specific scenario in mind!
