Which statement about the physical change of liquid water boiling into steam is true? The heat added represents an energy change.
The action cannot be reversed.
The steam cannot conserve mass.
The weight lost represents a mass change.
Subject I s SCIENCE. I had to chose CHEMISTRY becasue it wouldn't let me move on

The heat added represents an energy change.

Explanation:

In this process, the heat added is the energy change needed for this phase change from boiling water to steam.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

the temperature of the gas, in k, not celsius.
