evaporation
No. Steam is water vapor. Steam is formed by boiling water, which is a physical change.
The change of water to steam is a physical change, not a chemical change. In this case, the water molecules are simply changing phase from a liquid to a gas, but the chemical composition of water remains the same.
Water changing to steam is an example of a physical change, specifically a phase change from liquid to gas. This change is reversible as the steam can condense back into water under certain conditions.
False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.
Heat from the nuclear reaction changes water to steam.
Cool it!
evaporation
No, boiling water to make steam is a physical change, as it can be reversed by cooling the steam back into water. The water molecules remain the same substance throughout the process.
The formation of steam from boiling water in a kettle is a physical change. It involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.
Heat from the nuclear reaction changes water to steam.
The change from liquid water to steam is a physical change in the state of matter. Evaporation is the term for a liquid becoming a gas.
