what do these two changes have in common? water vapor condensing on a bathroom mirror sanding a piece of wood select all that apply. both are only physical changes. both are chemical changes. both are caused by heating. both are caused by cooling.

Answer

Brief Explanations:

Water vapor condensing on a mirror is a physical change as only the state of water changes from gas to liquid without a change in chemical composition. Sanding wood is also a physical change as it only alters the physical appearance and shape of the wood, not its chemical makeup. Neither is a chemical change, and neither is specifically caused by heating or cooling in the described processes.

Answer:

Both are only physical changes.
