What will happen when an ice cube floating in a glass of water fillef to the brim begins to melt?

Answer 1

The level stays the same.

Answer 2

your question has 2 aspects. first, became the glass filled to the brim earlier putting interior the ice-dice. for that reason, honestly the water would flow out of the glass. second, if the glass is filled as a lot because the brim after puting interior the ice dice. for that reason, there are 2 opportunities. once you're including the ice into the water, the quantity of the ice-dice is blending with the quantity of the water, for this reason raising the water factor to the brim. if there are not any air bubbles trapped contained in the ice-dice the point of water will stay an similar (reckoning on the temperature and evaporation situations). yet when there's a an air bubble trapped contained in the ice-dice, after the ice melts the water factor will drop to tutor quantity, would nicely be truly minute, yet nevertheless will drop.(as even air has quantity, for e.g. in a baloon).

Answer 3

The water level stays constant

Archimedes principle: a floating object displaces a volume of liquid whose mass is equal to the mass of the floating object.

The H20 in the floating ice cube will displace an equal volume of water whether it is frozen (in which case it takes up more space, some of which floats above the water) or if it turns to water itself.

Bonus answer: so why is everyone panicked about the polar icecaps melting if melting floating ice doesn't cause the water level to rise? Because a lot of the ice isn't floating--especially in the south. If it melts and runs into the oceans, Florida disappears.

Answer 4

It depends on the initial temperature of the water.
Let's take 1kg of ice at 0C. The melting ice would require 334kJto all melt, the specific heat capacity of water is about 4kj/kg so to drop the temperature 4C would require 16kj/kg. So we can chill about 20.875kg of water with 1kg of ice. But the density of water at 0C is 0.998 of the value at 4C.

So we'd get about a 0.2% increase in volume.

If the water was warm, say 45C then the density would increase from 990.2 to 991.9 so the volume would decrease about 0.17%.

So it depends.

Answer 5

I think it will go down slightly. When water freezes it expands, so when it melts it will contract causing it to take up less space.

Answer 6

the level Will go down, the reason is that water of 4 degrees Celsius has the lowest density.

Answer 7

nothing, the water is already dispalced with the ice cube.

Answer 8

nothing, the water level will remain the same.
