So evaporate?
"Evaporate" is not a direct antonym of "condense," but it can relate to the process of converting a liquid into vapor, which is a form of expansion. The more precise antonym for "condense" in terms of size or volume would be "expand." However, in a broader context, "evaporate" can imply a loss of mass or transition to a gas, which is a different concept. If you’re referring to the physical state change, "evaporate" could be considered in that context but isn't a direct opposite.
