The controlled variable is the variable that remains the same throughout the whole experiment. Here, the warm water and the same dishes are the same throughout the whole experiment- so they are the controls
No it is redistributed and the state changes to gas and liquid

Ionic compounds are compounds that are composed of oppositely charged ions, anions and cations. The force which holds the two ions (charged atoms) together is called the electrostatic force, and the bond that exists between them is called an ionic bond.
An ionic bond can be formed after two or more atoms loss or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and non metals, gaining electrons.
Monoatomic elements are elements that are stable as single atoms. The chemical elements which are stable single-atom molecules at standard temperature and pressure (STP) are noble gases. These are helium, neon, argon, krypton, xenon, and radon.
Ionic compounds are made up of oppositely charged ions which are held together by strong electrostatic force of attraction. Due to this reason, they are hard solids.
