Which of the following statement about ice melting is true A energy flows from the ice to its surroundings B water molecules move from their fixed position C water molecules lose energy?
the answer.when water freezes it turns into ice.ices particles are in a fixed position.when heat is aplied to the ice it melts.now the particles are still close together but they have a little space in between them.so they move from their fixed position.get it?
Why does an ice cubes volume expand?
Ice expands because more hydrogen bonds are formed as water cools. Heat is given off, more hydrogen bonds are formed, and water molecules tend to stick together. The way water molecules link together is open, so more space is formed as ice forms, causing ice to expand.
What do the particles do when the water begins to freeze?
Short Answer:As water freezes the water particles particles move from a somewhat random (liquid) arrangement into a more orderly crystalline (ice) pattern and give up energy in the process.Explanation:Water freezes (at 0 degrees C, 32 degrees F) and liquid water and solid water coexist at the same during the freezing process. In the liquid portion, molecules are still rather mobile, moving around in an irregular diffusive process. In the solid form, molecules are arranged in a regular pattern, the crystalline patter of ice. In the crystal state, the individual molecules stay in specific positions relative to their neighbors.It is important to note that the kinetic energy of water molecules is proportional to temperature, so the kinetic energy of the ice water molecules is the same as the kinetic energy of the water molecules at the freezing temperature, 0 C. The heat that is removed from water to form ice is potential energy that exists as a consequence of the electrostatic forces between the molecules. The potential energy decreases when the molecules move into positions where attractive forces hold them together more effectively.
Do molecules of ice have less mass than the molecules of water?
Mass is just "the amount of stuff there is". We can measure it in kg. If I have 4kg ice and 4kg water, then the answer is "no", but I could just as easily have 4kg of ice and 5kg water, in which case the answer is "yes". If you mean "does freezing water make it heavier?", then the answer is no - 4kg water makes 4kg ice, and they will weigh the same. However, ice has a greater volume than water*, so freezing water will make it expand. *This is not true for every liquid/solid combo.
Which form of water has particles moving the slowest?
Ice has particles moving the slowest among the three forms of water (solid, liquid, and gas). In the solid state, water molecules are held closely together in a rigid structure, causing them to vibrate in place rather than move freely. This results in slower particle movement compared to liquid water, where molecules are able to move past each other more easily.
What is statements about ice melting?
Water molecules move from their fixed positions
Describe what is happening to water molecules as ice melts?
they move faster
Are the molecules in ice packed more tightly than the molecules in water?
Compared to a solid object's molecules no. Unless the water is ice. Water molecules are more compact than gaseous molecules.
What is the difference between the water from melted ice and the ice itself?
The water from melted ice is in liquid form, while ice itself is in solid form. The water molecules in liquid water have more energy and are able to move more freely compared to the tightly packed ice molecules.
How do ice water molecules differ from warm water molecules?
The main difference is that ice water molecules have very low kinetic energy, i.e. they don't move very fast, compared to warm water molecules. The other difference is in the intermolecular forces holding the molecules together. They are greater in ice than in warm water.
What Statements about ice melting is true?
Water molecules move from their fixed positions
What is the phase of the ice molecules?
Ice is a molecule of water (H2O) in the solid phase.
Why does ice still melt in water?
Fire is pure energy being released. And it takes energy to move molecules around. Where ice is concerned, the water molecule has been sapped of all energy which causes it to remain in place and stick to other water molecules.. When the energy from fire comes in contact with the water molecule, the molecule absorbs the energy which causes the molecules to break away from each other and move. When the molecules break away and move is what causes a solid like ice to become a liquid.
What happens to water molecules as ice melts in terms of kinetic molecular thery?
As ice melts, the water molecules gain kinetic energy, causing them to vibrate more rapidly and break free from the rigid crystalline structure of the solid ice. This increases the molecular motion and allows the water molecules to move more freely, transitioning from a solid to a liquid state.
When ice melts what happens to the molecules?
They start to break their bonds of the solid. Water is unique and when it transforms from liquid to solid, it traps air between its molicules. When ice turns to water, it lets that air out so shrinks slightly. The result is at a higher temperature of 0 degrees Celsius, water is formed.
What is the different between ice and water?
Ice is the solid form of water, while water is the liquid form. Ice has a crystalline structure with molecules that are more tightly packed, whereas water molecules in liquid form are more loosely packed and free to move around.
Why energy is needed to melt ice and how this is explained by the structure of ice and water?
Think about how ice melts into water. By adding heat! Heat is a form of energy, and by adding heat, we can change ice to water. This is explained well by the structures of ice and water. Ice is a solid, and its molecules form rigid networks with space between molecules and are not easily broken. Water is a liquid, and its molecules are constantly moving around one another, leaving little space between molecules. Therefore, when heat energy is added to ice, the rigid bonds between molecules in the ice break, and they are free to move like a liquid.
