Why does heating a metal wire affect its electrical resistance? It decreases resistance because a metal becomes a superconductor when warmed. It decreases resistance because atoms at higher temperatures jostle into the way of moving electrons. It increases resistance because atoms at higher temperatures jostle into the way of moving electrons. It decreases resistance because higher temperatures free more electrons to carry current
