WebDrop an ice cube into the cylinder. It will float (just) on top of the oil. Observe the cube. As it melts, the water that is formed makes a droplet attached to the cube. Eventually this detaches itself from the cube and sinks, joining the water layer below. This illustrates the anomalously greater density of water compared to ice.

Web22 de fev. de 2013 · Most of us are familiar the melting point of ice: 0 degrees Celsius or 32 degrees Fahrenheit. If the temperature of ice is below this number, it will stay solid; if the temperature of the ice is increased above this number, the ice changes to liquid water. If ice comes into contact with water, we know the ice must be below 0 degrees Celsius and ... Web19 de out. de 2024 · Since the ice cube is approximately 90% as dense as the 0 deg C water that it is floating in, approximately 10% of the ice cube will be above the water surface before it melts. When the ice cube is fully melted, it contributes its weight to the water in the container that it was floating in, which is exactly equal to the weight of the ice cube. east peoria city council
