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.
The colder the water, the slower the molecules move and the tighter they are together.
Ice molecules are fixed in position.
The lower the temperature, the more close the molecules will be. Therefore the will be less molecules in ice than in water. So water will have more molecules per litre.
due to hydrogen bonding bettween water molecules.
Heat will travel from the person's hand into the ice pack, where it will excite the molecules there and warm the ice pack.
Ice is a molecule of water (H2O) in the solid phase.
As the ice melts, the water molecules gain energy, causing them to move more quickly.
The molecules remain identical (for example ice, water, vapors).
They are made of different kinds of molecules.
Molecules in warm water are moving faster than those in the colder water.
Rain is liquid Ice is solid. with water when you cool it (slow the molecules) it expands (which is unique to water) becoming a solid crystal, and since it expands its mass per volume ratio has changed making it less dense then liquid water.
ice melts in warm water because ice is slow moving molecules so slow they practically vibrate wen heat is added is like Coffee it wakes them up and energizes them cousing them to melt into a liquid
They are made of different kinds of molecules.
Heat is not a "thing," it is not transferred from object to object. Instead, when an object is cold, its molecules vibrate slower than when it is warm. When a warm object comes in contact with ice, the fast-moving molecules of the warm object transfer some energy to the ice. This is why the ice warms up, and the warm object cools off (due to losing some of its molecules' energy).
No, the ice molecules in ice are not ionized.
Compared to a solid object's molecules no. Unless the water is ice. Water molecules are more compact than gaseous molecules.
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.
No, when water turns to ice, no new molecules are formed. The molecules in water rearrange themselves into a crystal lattice structure when they freeze, but the individual water molecules remain the same.
Water is liquid, ice is solid. Water is usually warmer than ice.
