Final answer:
When ice cubes are added to water, they cause the temperature of the water to decrease. The hotter the water initially, the longer it takes for the water to cool down with ice cubes. Cold water may not show a significant change in temperature when ice cubes are added.
Step-by-step explanation:
When ice cubes are added to normal water, they will cause the temperature of the water to decrease, eventually turning it into cold water. The ice cubes absorb heat from the water, causing the water molecules to lose energy and slow down.
When ice cubes are added to lukewarm water, they will also cause the temperature of the water to decrease, but it may take longer for the water to reach the same level of coldness as the normal water. This is because the lukewarm water already has some heat, so the ice cubes need to absorb more energy to cool it down.
When ice cubes are added to cold water, there may not be any noticeable change in the water temperature, as the water is already at a low temperature. The ice cubes may melt slower in cold water compared to normal or lukewarm water.
