Question

if a apple is left out for 270 days would that be a physical change or a chemical change?

Answer 1

If an apple is left out for 270 days, the changes that occur are primarily chemical changes rather than physical changes.

A physical change would involve changes in the state or appearance of the apple without altering its chemical structure (e.g., slicing the apple or drying it). In contrast, when an apple is left out for an extended period, it undergoes processes such as rotting, decomposition, and fermentation, which involve breaking down the organic compounds within the apple. These processes involve changes at the molecular level, indicating chemical changes.

In summary, the changes that occur to an apple left out for 270 days are primarily chemical changes due to decomposition and decay.
