What energy change occurs during condensation? Please answer, i’ll give you brainliest !

Please see Explanation and Attachment (Heating Curve for Water)

Explanation:

Energy change associated with phase change in substances is either endothermic (energy added to system) or exothermic (energy removed from system). Condensation is but one term in six (6) describing phase change occurring when energy change is involved. The following table, in general, summarizes the related effects of energy change as applied to phase change.

Process                   Phase Change         Energy Change*

Condensation         gas => liquid             Exothermic

Evaporation             liquid => gas            Endothermic

Freezing                  liquid => solid           Exothermic

Melting                    solid => liquid            Endothermic

Sublimation            solid => gas                Endothermic

Deposition              gas => solid               Exothermic

* Energy Change terms:

Endothermic => Addition of heat energy

Exothermic => Removal of heat energy

here's the link to your question!

explanation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
