Is it physical or chemical when ice melts?
When ice melts, it undergoes a physical change, not a chemical change. The molecules in the ice are still the same water molecules, but they are transitioning from a solid state to a liquid state.
Classify as chemical and physical change-freezing of water?
Freezing of water is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of water. The molecules in water rearrange to form a crystalline structure in the solid state but remain as H2O molecules.
Is water turning to snow a chemical or physical change?
Changes of state are physical changes.
Do water molecules in the liquid state have more energy than water molecules in the polar state?
Do water molecules in the liquid state have more energy than water molecules in the polar state
Why is ice in liquid water at 0 degrees an example of physical equilibrium?
This is an example of physical equilibrium, because if you look at the two phases (physical property) of water at zero degrees C, they both exist. At 0ºC, the molecules of water go back and forth between being a liquid and a solid, thus the equilibrium.
How do the molecules in solids liquids gases differ?
The molecules remain identical (for example ice, water, vapors).
Which occurs as the kinetic energy of water molecules increase?
As the kinetic energy of water molecules increases, the temperature of the water also increases. This results in water molecules moving faster and further apart, leading to changes in the physical state of water (solid to liquid to gas).
Is water vapor condenses to form rain chemical or physical?
The condensation of water vapor to form rain is a physical change because the water molecules are simply changing from the gaseous state to the liquid state without a change in their chemical structure.
How is freezing water to make ice cubes a physical change?
Freezing water to make ice cubes is a physical change because it involves a change in state from liquid to solid without altering the chemical composition of the water molecules. The molecules in water reorganize to form a crystalline structure when frozen, but they remain the same H2O molecules.
What is the figure that gives the number of identical molecules in a formula?
The subscript in a chemical formula indicates the number of identical molecules present. For example, H2O indicates two molecules of water present.
Is it a chemical or physical change when you freeze water?
Freezing water is a physical change because the molecules stay the same, only changing from a liquid to a solid state. Chemical changes involve the rearrangement of atoms or molecules to form new substances.
Is water condensing a physical or chemical change?
Water condensing is a physical change. It is a change in state from the gaseous phase (water vapor) to the liquid phase (liquid water) without any change in the chemical composition of water molecules.
