Melting and boiling are reversible changes produced by heat.

Answer 2

MATERIALS UNDERGO CHANGES DUE TO OXYGEN AND HEAT ARE​

• Oxygen is an O-marking chemical with a total of 8 atoms.
• Therefore, substances undergo changes before Oxygen through the oxidation process.
• When a sufficient amount of oxygen is present in the air.
• When there is a small amount of oxygen.
• In this case, no heat is required.
• Is anything that makes up anything, happens, is complex, and is made up of atoms.
• Physical Changes and Chemical Changes are nothing new being created, although the topic may take a different approach.
• Factors That Change Due to Oxygen and Temperature. Other worksheets for this concept are the key concept is the deterioration of machinery and chemicals, the effects of heat in the story, the chemistry of the problem-solving book.
