What do these two changes have in common? using a large magnet to remove pieces of iron from a junkyard breaking a ceramic plate Select all that apply. Both are only physical changes. Both are chemical changes. Both are caused by heating. Both are caused by cooling.

## Step 1<br />The problem presents two different scenarios: using a large magnet to remove pieces of iron from a junkyard and breaking a ceramic plate. We are asked to identify the commonality between these two changes.<br /><br />## Step 2<br />The first scenario involves using a large magnet to remove pieces of iron from a junkyard. This is a physical change because the iron pieces are not chemically altered or transformed. They are simply moved from one place to another.<br /><br />## Step 3<br />The second scenario involves breaking a ceramic plate. This is also a physical change because the ceramic plate is not chemically altered or transformed. It is simply broken into smaller pieces.<br /><br />## Step 4<br />By comparing the two scenarios, we can see that both are physical changes. They do not involve any chemical reactions or transformations.
