Based on Jasmine's experiment of adding varying amounts of ice to samples of water, the most reasonable conclusion would be:
As ice added increases, the change in water temperature increases.
This conclusion suggests that more ice leads to a greater change in the water's temperature, typically cooling it further as ice absorbs heat from the water. The other statements about water temperature and the kinetic energy of water molecules are not accurate; as water temperature increases, the kinetic energy of the water molecules also increases, and as water temperature decreases, the kinetic energy decreases.
