x litres of water and cool it to solid ice(say
0 degree) and measure the volume of ice as
V1 liters. Now you let this ice melt at room temperature for some time
T1 and measure the volume of water after melting as
V2 litres. Will it reduce or increase or be the same ?
V1 litres of solid ice (say
0 degrees) floating in water. When it melts, what happens to the volume of the system (water + ice in a container) ? Does it increase or decrease or remains the same ?
Repeat case 2, except that you tie the ice cube to the bottom of the container. Now, does the water level increase or decrease or remains the same ?
In case 2, when ice is floating, the water level remains the same, floating ice displaces water equivalent to its weight. Mass of the system is unchanged, so water level remains the same.
In a contradiction, if the system (water + ice) is isolated, they come to the equilibrium position between ice and water. Ice contracts till
4degree Celsius and expands after that, water contracts as temperature drops. This confuses me as to decide upon what will happen to the volume of the system.
In first case, the volume is reducing till
4degree celsius and increasing after that. At what temperature will the volume of water be the same as volume of ice ?
