how does an ice cube melt?

Question

Hi,
im doing a project on how does an ice cube melt.This is my task:

To describe what happens to an ice cube when it is left out of the freezer and explain why this happens.

i have to do a project explaining it on a poster. how does it melt? is it like the heat energy breaking it?On my sheet it says:

You may find drawing diagrams and labelling them with your ides it is helpful.
Try to include as much info about particles and energy in your explanation.
Think about the particles inside the ice cube: how are they arranged? What happens to them as the ice melts?Why does this happen?

Please, if you can help, it would be GREATLY appreaciated. if you can- do.please. i really need this.

thanks so much

(by the way im this usernames daughter)

:)

how does the heat energy affect the ice cube?

Try and do your own homework. isnt helpful.

im looking thru every book of mine- so iz mi mum n dad. plz- i need about how heat energy affects it. does it bounce of and break off the ice particles?

cheers

Answer 1

The heat just makes the H2O particles change from their solid state (ice) to their liquid state (water) and if enough heat is added it would then again change to it's gaseous state (steam). Beyond this you should really do your own homework - read your text book and watch some ice melt. Not exactly exciting but you might actually learn something.

Answer 2

If, for example, you take 1 lb of ice at freezing point (32 degrees Fahrenheit) and let it stand in a container, heat from the surroundings will cause the ice to: -

1. Melt to 1 lb of water by the absorption of 144 BTU of heat energy. However, at this point, the temperature does not change it remains at 32 degrees Fahrenheit.

2. Then, for each BTU absorbed, the temperature of the water will increase by 1 degree Fahrenheit.

Answer 3

well ask yourself is an ice cube solid...then is it solid when it melts.. and where any heat that tranforms it comes from.....ie would it melt in the freezer?..would it melt in a cool room? and would it melt in a hot room?...the melting is always the same..ice to water..but the rate of melt is different...why...what is different between the freezer and a hot room or put another way which has more heat energy...and would the melting use some of that energy...ie would the room cool a bit.....think of your drink when you put icecubes in it.what happens

Answer 4

look up ice on wikipedia. It gives you some basics and links to other sites that have pictures of the molecular structure of ice crystals and things like that that you could put in a presentation.

Answer 5

You've got the anwer in your question. The teacher has given you a lot of instructions on how to do it.

Try and do your own homework.
