Ice Water

In summary, when a block of ice floats in water, it melts and the level of water in the beaker goes down.

What do you think and why?

i didn't went through the entire thread but i think that the floating piece of ice does puts some pressure on the surface of the water which may cause the surface of the water to rise when the ice cube melts the pressure is gone but the water level will not drop as the molten ice cube is converted to water itself so level of water not changes according to me i am not 100% sure if i am right so correction will be highly appreciated

<h2>1. How does the water level change in a beaker when ice melts?</h2><p>When ice melts in a beaker, the water level will increase. This is because the volume of the ice is greater than the volume of the same amount of liquid water. As the ice melts, it takes up less space and therefore the water level rises.</p><h2>2. Why does the water level change when ice melts?</h2><p>This change in water level is due to the differences in density between ice and liquid water. Ice is less dense than water, meaning that it takes up more space for the same amount of mass. When the ice melts, it becomes liquid water which is more dense and takes up less space, causing the water level to rise.</p><h2>3. Does the amount of ice affect the water level in the beaker?</h2><p>Yes, the amount of ice does affect the water level in the beaker. The more ice there is, the greater the change in water level will be when it melts. This is because a larger amount of ice will take up more space when it melts, causing a greater increase in water level.</p><h2>4. How does pressure play a role in water level changes when ice melts?</h2><p>Pressure does not directly affect the change in water level when ice melts. However, as the ice melts and the water level rises, there may be a slight increase in pressure at the bottom of the beaker due to the weight of the water. This pressure increase is minimal and does not have a significant impact on the overall experiment.</p><h2>5. Can this experiment be replicated with other substances besides water and ice?</h2><p>Yes, this experiment can be replicated with other substances besides water and ice. Any substance that undergoes a phase change from solid to liquid, such as wax or butter, will exhibit similar changes in water level due to differences in density. However, the amount of change in water level may vary depending on the specific substance used.</p>
