Since ice is less dense than water, it floats on it, we all know this. Now suppose, if ice is floating in a glass cup, when the ice melts there should be some change at water level in the glass cup. But when I found this on the internet, it states that the water level will be same. Can someone justify/explain this?
In my way, water level will decrease because ice has greater volume than water, so when it floats, it will displace some water equal to its volume for floating. But when it melts, its volume decreases and hence water level will also decrease. Is it right or wrong what I am thinking?
