nope. you drop ice into water. no chemical reaction just physical change (ice melts) and that takes heat so the water is cooled.

Usually would be a better term. Always means NO exceptions, and the dissolving of one substance in another may not be a chemical reaction, involving molecular change, but can result in temperature change.

YES A CHEMICAL REACTION DOES OCCUR WHEN THE TEMP CHANGES IE THE HEAT FROM THE GULF STREAM NEEDS A CHEMICAL REACTION TO OCCUR FOR THE GULFS HOT AIR TO TRAVEL SO FAR ,
A REACTION HAPPENS ALWAYS BECUASE CHEMICALS IN THE ATMOSPHERE NEED TO INTERACT WITH EACH OTHER FOR THE WEATHER TO HAPPEN, HURRICANES, TORNADOS , HEAT, COLD AND EVEN SNOW.
EVEYTHING IN THE UNIVERSE IS A CHEMICAL REACTION, THATS HOW WE ARE ALL HERE INCLUDING THE EARTH AND ALL THAT BELONGS TO IT.
