A Venn diagram is used to compare and contrast different topics. The items that are unique to each topic are represented in the

separate sections of the circles, and the items that are common to both topics are represented in the center overlapping sections. Harlow creates this Venn diagram comparing and contrasting endothermic and exothermic processes. What can be added to the Examples section of each circle? A) Endothermic: ice melting into water, and a heat pack becoming warm
Exothermic: a glow stick glowing, and fireworks exploding
B) Endothermic: ice melting into water, and an instant ice pack turning cold
Exothermic: fireworks exploding, and gasoline burning
C) Endothermic: a glow stick glowing, and a heat pack becoming warm
Exothermic: an instant ice pack turning cold, and ice melting into water
D) Endothermic: gasoline burning, and an instant ice pack turning cold
Exothermic: ice melting into water, and an instant ice pack turning cold

An exothermic reaction is one in which there is the production of heat whereas an endothermic reaction is one in which heat is absorbed. For the choices above, the answer would be letter B. Ice melting in water and an ice pack turning cold absorbs heat which is why it is an endothermic reaction. Exploding fireworks and gasoline burning gives off heat which is why it is an exothermic reaction.
