Answer:
The 14°C sample is more dense than the 25°C sample.
Explanation:
Warm water rises, cooler water falls. Warm water is less dense than cooler water. The actual density of water changes about .4% as the water temperature changes from near zero at 0°c up to about 30°c. That may not sound like much. However, that is enough density change for cold water to flow below warm water. This can have an impact on ocean currents and other phenomena in the ocean.
