Describe how the structure of the molecules in a solid change as it becomes a liquid?
In a solid, the molecules are tightly packed in a fixed arrangement, vibrating in place. As the solid melts and becomes a liquid, the molecules gain enough thermal energy to break free from their fixed positions and move more freely. This creates a less ordered structure and results in increased fluidity.
What happen to the atom or molecules of a substance when it melts?
The intermolecular forces are weakened.
When ice melts what happens to its chemical composition?
When ice melts, the chemical composition remains the same. Ice is just the solid state of water, so when it melts, it turns into liquid water. The molecules in ice rearrange themselves into a more disordered state to become liquid water, but the chemical makeup of the water molecules themselves does not change.
What substance melts at 20 degrees what type of structure?
Water melts at 0 degrees Celsius, not 20 degrees. Water has a hexagonal close-packed structure when it is in solid form.
What happens to an ice cubes particles when the ice cube is melting does the weight remains the same?
As the ice cube is solid , the particles are tightly packed together but as it melts it changes to a liquid so the particles change so that they are like particles in a liquid. the mass is conserved ( stays the same)
When ice is melted the volume of the ice decreases?
When ice melts, it transforms from a solid to a liquid, which results in a decrease in volume. The molecules in the solid ice are packed more tightly than in the liquid water, leading to a lower volume when the ice melts.
What happens when ice melts?
It turns into water and the molecules becomes less densely packed
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 happens to crystal lattice as ice melts?
The arrangement of water molecules start having their chemical bonds break as ice melts. Hydrogen bonds constantly form and break constantly moving everything out of position.
What happens to the molecules in a liquid when it melts?
When a solid melts, intermolecular forces that were holding the molecules tightly together are overcome by the kinetic energy introduced by heating the substance. All of the molecules are still present; they are just more widely dispersed and can move more freely, causing the fluid properties of liquids.
What happen to the atom or molecules of a substance when it melts?
The intermolecular forces are weakened.
Why do ice cubes melt faster in water?
ice is water so water plus water equals more water!
What is the temperature of ice and how does it affect its physical properties?
The temperature of ice is 0 degrees Celsius. When ice is at this temperature, it is in a solid state. The low temperature causes the molecules in the ice to be tightly packed together, making it rigid and hard. As the temperature increases, the ice melts and turns into liquid water, which has different physical properties than solid ice.
What happens to the arrangement of water molecules as water melts and freezes?
When water melts, the molecules go from a more ordered, structured arrangement in the solid state to a less organized, more fluid arrangement in the liquid state. During freezing, the molecules transition back to a more structured arrangement as they form a solid state.
How does the density change from solid to liquid to gas?
The density generally decreases as a substance transitions from solid to liquid to gas. In the solid state, particles are tightly packed resulting in higher density. When the substance melts into a liquid, the particles become less ordered and the density decreases. As the liquid is further heated to form a gas, the particles are further apart, leading to the lowest density.
When ice melts what happens to its chemical composition?
When ice melts, the chemical composition remains the same. Ice is just the solid state of water, so when it melts, it turns into liquid water. The molecules in ice rearrange themselves into a more disordered state to become liquid water, but the chemical makeup of the water molecules themselves does not change.
