Help me in this science homework please ...?

Question

Ok in school we did a expirement on how temeperature changes when u drop an ice cube in a waer and it melts but for homework they ask me "BASED ON THE KINETIC THEORY F ENERGY EXPLAIN WHAT HAPPENS TO ICE AS IT MELTS INTO A WATER LOOK UP KINETIC THEORY OF MATTER " I think its particles move away bc it is getting used and pushed off the ice to get used and camaflouged to the normal water temperature before dropping in the ice cube, am i correct if not please help its due tommorrow ...... HELP!!!!!

Answer 1

first of all, you have to define what kinetic theory is.

kinetic energy is a type of energy expended by a moving object, or energy of motion. you might be wondering how ice can move.. well, it is because all molecules move, they vibrate in small amounts in solid. Liquid has a loose arrangement of molecules, and move around a particular container like the pong game in the computer, ricohet-ing about.

ice is in very low temperatures. and water has a higher temperature than that of ice. thus, water is the heat source for the ice.

heat causes molecules to get "excited". so, the compact molecules of the icebecome more excited and go from small vibrations to more of a fireworks dispersal. that is why they melt. the molecules of the solid ice get excited enough to join the liquid molecules. when all the ice is melted, the molecules are in a homogenised state.

now, give more heat on the water, the molecules will get super excited and become steam (water vapour gas). they are more in a frenzy than liquid at this point.

Answer 2

Kinetic energy involves the transfer of energy from one object to another. In this case, the energy involved is heat. The molecules of the warmer water are moving around at a faster rate than the molecules in the ice cube. As they move around, they bump into the molecules of water in the ice cube, and a little of their energy is transfered to the ice water molecules. They in turn move, the heat released in the transfer raises the temperature around the ice cube molecule- and frees it to join the molecules in the liquid water. Eventually there are no more ice cube molecules to bump into, and the temperature of all the molecules in the water become the same temperature- left long enough the water in the container will be the same temperature as the air in the room around it.

Answer 3

Kinetic theory of matter has to do with the movement of molecules and how they collide, causing heat and pressure. The molecules of the water move faster than the frozen ice cube, whose molecules are moving very slow. The waters molecules collide with those of the ice cubes, causing heat and making the cubes molecules move faster, melting the cube. However, as the cubes molecules are dispersed, the slow molecules of the cube make the waters molecules slow down with their slow speed collision. This is what makes water colder.

Answer 4

The three states, or phases, of matter are solid, liquid and gas. When a substance changes from one state of matter to another, it has undergone a change of state (change of phase). The ice cube, is a solid and rigid substance with molecules very close together.
As it melts into water- the molecules move further apart then in a solid. So, the melting causes a change in intermolecular distance.

Answer 5

The particles of cold water in the ice cube start to gain energy as the warmer water surrounds it, and they begin to flow and mingle with the tepid water.
I beleive that's more or less correct.

Answer 6

What happens to the particle motion when ice changes to steam?

I have many ideas help me find one. I am only a first grader and my school is giving me 6th grade science, english and math. :(

Answer 7

nicely enable me only whip out the ole McDougal Littell Earth technology e book I have in my closet o wait, maximum folk answering this don't have your textbook the questions will be large

Answer 8

Finally . . . a kid who is asking for homework help but actually tried to do it themselves. That's what there supposed to do! Good job :-)

But as for the actual question . . . I dunno (lol).
