## Step 1<br />The problem involves understanding the nature of two changes: beating an egg and a crayon melting in the sun. <br /><br />## Step 2<br />Beating an egg is a physical change. This is because the egg's composition does not change; only its physical state does. The egg's mass is conserved in this process.<br /><br />## Step 3<br />A crayon melting in the sun is also a physical change. The crayon's composition does not change; only its physical state does. The crayon's mass is conserved in this process.<br /><br />## Step 4<br />Based on the above analysis, both changes conserve mass and are physical changes.
