Question

if you fill a glass to the brim with ice water , ice melts what will happen​

Answer 1

Answer:

The pressure increase hence the ice melts

Answer 2

When the cube melts, the surrounding liquid can move into the space it filled. If the glass contains only ice and water, it will not overflow because the amount of extra water will be equal to that previously displaced by the cube(s). Diluted soda is slightly denser than water due to its sugar content
