The correct answer is "Both are caused by heating".
Explicação
## Step 1<br />The problem asks us to identify the commonality between two processes: baking cookies and water evaporating from a puddle. <br /><br />## Step 2<br />Baking cookies is a chemical change. This is because the ingredients in the cookie dough undergo a chemical reaction when exposed to heat, resulting in the formation of new substances (the baked cookies).<br /><br />## Step 3<br />Water evaporating from a puddle is a physical change. This is because the water molecules simply change their state from liquid to gas, but they remain the same substance.<br /><br />## Step 4<br />Therefore, the statement "Both are only physical changes" is incorrect.<br /><br />## Step 5<br />The statement "Both are chemical changes" is also incorrect. While baking cookies is a chemical change, water evaporating from a puddle is a physical change.<br /><br />## Step 6<br />The statement "Both are caused by heating" is correct. Baking cookies requires heat, and water evaporates from a puddle when exposed to heat from the sun or other sources.<br /><br />## Step 7<br />The statement "Both are caused by cooling" is incorrect. Neither process is primarily caused by cooling.
