During which process of the water cycle dose water change from a gas to a liquid1. precipitation 2. condensation 3.transpiration4. evaporation

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

fe 55.85 g/mol and h2o 18.02 g/mol.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
