Luis set a glass of ice water out side is the sunshine . when he looked at the glass 10 minutes later, the contents had changed.
abruzzese [7]

well its evaporation cuz it the suns heat heated the ice to the point where it turned to a gas, it could be conduction cuz the heat of the sunshine conducted the ice and turned it to a gas but that would be evaporation too so its not onduction, its not a chemical change cuz theres no new molecule the substance is itself, and its not a sudden change obviously

so the answer is A. evaporation~~~
