What else can I help you with?
What change of state and what energy changes occur when water freezes?
the state change is from liquid to solid and the energy change is cold energy to heat energy
The evaporation of water is an example of a change in?
The evaporation of water is an example of a physical change, where water changes from its liquid state to a gaseous state without any change in its chemical composition.
What is it when water changes to water vapor?
When water changes to water vapor, it has changed its state from liquid to vapor and no chemical change has taken place. It's only a physical change.
When ice changes to water the link up of atoms does or does not change?
The bonds between hydrogen and oxygen atoms of individual water molecules do not change when liquid water changes to ice. This is a physical change called freezing, and does not cause any chemical changes to occur. Only chemical changes can cause changes in chemical bonds.
What causes water to change to a different state?
Water changes state depending on its temperature and pressure. When water is heated, it can change from a solid (ice) to a liquid (water) to a gas (steam). When water is cooled, it can go from a gas to a liquid to a solid. These changes in state are due to the energy levels of the water molecules.
Is water being boiled a chemical change or physical change?
It is a physical change because the water only changes its state from liquid to gas.
What are the examples of a physical changes?
Change of the state of water from a solid (ice cubes) to liquid (water).
Why is the boiling point of water a physical change?
It's not a chemical change because the only the temperature and phase changes. The properties may be altered somewhat, but it the same chemical compound. No atomic bonds are broken or formed, there are no new substances formed, and none of the signs that indicate a chemical change are present. Some of the water is changing from a liquid to a gaseous state, and can be returned to a liquid state, unchanged, by cooling it.
What is the change of state does melting change from?
From a solid like ice to a liquid like water.
Is the conversion of liquid water into gaseous water is a chemical change?
No, the conversion of liquid water into gaseous water is a physical change, not a chemical change. This process, known as evaporation, involves only a change in the physical state of the water molecule, not its chemical composition.
What change of state occur when a puddle disappears?
The change of state that occurs when a puddle disappears is evaporation. The liquid water in the puddle turns into water vapor and escapes into the air.
Why is boiling water considered a physical change?
Because it physically changes from a liquid state to a gaseous state.
