- Evaporating is a kind of phase change
- Condensing is a kind of phase change
- Therefore, evaporating and condensing are both phase change

- Evaporating and condensing are both phase change
- Temperature changing can cause phase changes
- So, evaporating and condensing can both be caused by temperature changing

- Evaporating and condensing can both be caused by temperature changing
- Temperature is a measure of heat energy
- So, evaporating and condensing can both be caused by the change of heat energy

So, evaporating and condensing can both be caused by the change of heat energy
Q: In which way are evaporation and condensation similar?
Context:
- Evaporating is a kind of phase change 
- Temperature is a measure of heat energy 
- Temperature changing can cause phase changes 
- Condensing is a kind of phase change
