The answer is (2) Copper. Because copper is consist of atom. If it is decomposed, the atom will be changed. While chemical change is just the break down and form of chemical bonds between atoms.

Answer:
Metal oxides are compounds composed of metal ions and oxide ions. Nonmetal oxides are compounds composed of nonmetal atoms and oxygen atoms. The main difference between metal oxides and non metal oxides is that metal oxides are basic compounds whereas nonmetal oxides are acidic compounds.

Answer:
                The volume is increased.
Explanation:
                      According to <em>Charles' Law</em>, " <em>at constant pressure the volume and temperature of the gas are directly proportional to each other</em>". Mathematically this law is presented as;
                                                     V₁ / T₁ = V₂ / T₂   -----(1)
In statement the data given is,
T₁  =  10 °C  =  283.15 K                    ∴  K  =  273.15 + °C
T₂  =  20 °C  =  293.15 K
So, it is clear that the temperature is being increased hence, we will find an increase in volume. Let us assume that the starting volume is 100 L, so,
V₁  =  100 L
V₂  =  Unknown
Now, we will arrange equation 1 for V₂ as,
                                                     V₂  =  V₁ × T₂ / T₁
Putting values,
                                      V₂  = 100 L × 293.15 K / 283.15 K 
                                      V₂  = 103.52 L
Hence, it is proved that by increasing temperature from 10 °C to 20 °C resulted in the increase of Volume from 100 L to 103.52 L.
