Steam is a vapor form of water when it reaches its boiling point and transitions from a liquid to a gas.
An analogy of steam could be that it is like a cloud. Just as steam is the gaseous form of water resulting from heat, a cloud is a collection of water droplets or ice crystals suspended in the atmosphere. Both steam and clouds involve water changing state in response to temperature.
If a gas is produced and it isn't a state change (such as steam bubbles forming), the reaction is a chemical change because the molecular makeup of either the water or the drain cleaner has changed and the hydrogen has been liberated.
