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.

The heat added represents an energy change is the true statement regarding the physical change of liquid water boiling into steam.  

Explanation:

         Physical change is the change of substance without affecting its composition. Likewise, water changes into steam when boiling reveals physical change activity. Water that reaches the boiling point has characteristics like liquid form, bubbles, and denser vapors.  

          This is because when heated, the water molecules receive extra energy from a heat source, vibrate and move faster. Simply, energy changes occur in water particles while heating. If the boiling does not stop, the process continues until all the water turns into gas.  

a The heat added represents an energy change.

Explanation:

i just took the test

in physics zero. in muscle fatigue could be high

i think the answer is a, hope this : )
