2. An ice cube at 0°C is placed in some liquid water at O'C, the ice cube sinks-Why? |
|
Answer» Ice cubes don’t sink in water, they float. If you add water to a bucket full of ice, then some of the ice will melt, bringing the water temperature down to 0 degrees Celsius. Every gram of ice that melts will reduce the temperature of 80 grams of water by one degree. Once the water is at 0 degrees, the rate at which the ice melts will slow down as it will have to adsorb [thermal] energy from outside the bucket, not from the water itself. |
