physical
Water cannot melt because it is a liquid. However, a snowflake or an icicle can melt because they are solid states of water.
You must understand that water can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).
Changing physical states is not a chemical change, but a direct result of heat or cold application.
Melting snowflakes is a physical change, not a chemical change. The water molecules in the snowflake remain the same chemical composition before and after melting, they just change from a solid to a liquid state.
The melting of ice in a drink is a physical change because the chemical composition of the ice (water) remains the same. The change is reversible since the ice can refreeze if cooled.
Melting solid ice into liquid water is a physical change. It involves a phase change from solid to liquid without altering the chemical composition of water molecules.
physical, because there is no chemical reaction to cause the change. it's just heat.
Melting ice is a physical change because the properties of the physical changes say that there is a physical change when the state of a material changes. the ice changes into water after melting .this is temporary change as the property says. you can change water back into ice by freezing.
Melting is a physical change.
Melting snowflakes is a physical change, not a chemical change. The water molecules in the snowflake remain the same chemical composition before and after melting, they just change from a solid to a liquid state.
First of all, melting point is not a change at all, so forget about classifying it as a physical or a chemical change. It's a property and it's got nothing to do with the chemical composition of water since when water melts it's chemical nature does not change. Hence melting point of water is a physical property or characteristic.
Melting ice is a physical change because it involves a phase change from solid to liquid without altering the chemical composition of water.
It is a Physical Change. Melting it does not change what components/elements are found in snow. It is just a phase change from solid to liquid.
Melting is a physical change.
Melting ice is a physical change because it does not change the chemical composition of the water.
The melting of ice in a drink is a physical change because the chemical composition of the ice (water) remains the same. The change is reversible since the ice can refreeze if cooled.
Ice melting is a physical change rather than a chemical change because the substance (water) remains the same at a molecular level. The process involves a change in state from solid to liquid due to the absorption of heat energy, with no alteration to the chemical composition of the material.
Melting solid ice into liquid water is a physical change. It involves a phase change from solid to liquid without altering the chemical composition of water molecules.
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
physical, because there is no chemical reaction to cause the change. it's just heat.
