What do these two changes have in common? baking cookies water evaporating from a puddle Select all that apply. Both are only physical changes. Both are chemical changes. Both are caused by heating. Both are caused by cooling.

Answer 1

The correct answer is "Both are caused by heating".

Answer 2

## Step 1The problem asks us to identify the commonality between two processes: baking cookies and water evaporating from a puddle. ## Step 2Baking 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).## Step 3Water 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.## Step 4Therefore, the statement "Both are only physical changes" is incorrect.## Step 5The statement "Both are chemical changes" is also incorrect. While baking cookies is a chemical change, water evaporating from a puddle is a physical change.## Step 6The 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.## Step 7The statement "Both are caused by cooling" is incorrect. Neither process is primarily caused by cooling.
