The second batch of cookies spread more due to a few key factors. First, the baking sheet was already warm from the first batch, which can cause the butter in the cookie dough to melt faster, leading to more spreading. Additionally, if there was any residual grease or oil left on the baking sheet, that could also contribute to the cookies spreading more than they did in the first batch. Lastly, the dough may have warmed up slightly while it sat out, making it less firm than when it was first placed on the baking sheet. All these factors combined lead to the increased spreading of the second batch.<|im_end|>
