what do these two changes have in common? a piece of pizza rotting in a trashcan firing a clay pot in a hot kiln select all that apply. both result in a different type of matter than was there before. both are caused by heating. both conserve mass. both are chemical changes.

what do these two changes have in common? a piece of pizza rotting in a trashcan firing a clay pot in a hot kiln select all that apply. both result in a different type of matter than was there before. both are caused by heating. both conserve mass. both are chemical changes.

Answer

Brief Explanations:

  1. New matter formation: In pizza - rotting, bacteria and fungi break down organic compounds in pizza to form new substances like carbon - dioxide, water, and other decomposed products. In firing a clay pot, high - temperature heating causes chemical reactions in the clay materials to form new ceramic compounds.
  2. Heating cause: Firing a clay pot is clearly caused by heating in a kiln. While pizza - rotting is mainly due to biological activity, heat (from the environment) can affect the rate of the rotting process.
  3. Mass conservation: According to the law of conservation of mass, in both chemical changes (pizza rotting and clay - pot firing), the total mass of the substances before and after the change remains the same, as atoms are just rearranged.
  4. Chemical change nature: Pizza rotting is a biological and chemical process involving decomposition. Firing a clay pot is a chemical process as the clay undergoes chemical reactions to change its physical and chemical properties.

Answer:

Both result in a different type of matter than was there before., Both are caused by heating., Both conserve mass., Both are chemical changes.
