Identify the process described: condensation is the change of state of a substance from gas to liquid.
Recall the states of water involved in cloud formation: water vapor (gas) in the atmosphere cools and changes to liquid droplets.
Understand that condensation is the opposite of evaporation, where liquid changes to gas.
Eliminate incorrect options: 'liquid to gas' is evaporation, 'liquid to solid' is freezing, and 'solid to liquid' is melting.
Conclude that the correct change of state when water condenses in clouds is from gas to liquid.
