In such houses, exposed water pipes can freeze on cold nights. Explain why it is that the hot water pipes and not the cold water pipes that freeze first if the temperature is not too much below freezing. ANS: Has to do with HenryТs Law. More gas can be dissolved in cold water than in hot water. The fp of water decreases as the concentration of solute Ц even gaseous solutes Ц increases. Soooooo even though water in the cold-water pipes may reach 0░ C firstЕ being closer to it to begin withЕ. The fp of the cold water is lower than the fp of the hot water for the presence of greater concentrations of the dissolved gases (in the cold). э78ьэ·°Ї°Дh & F78ь№·· ░╨/ ░р=!░"░#Ра$Ра%░ [4@ё 4NormalCJOJPJQJmH <A@Є б<Default Paragraph Fontэ       эээьШЪё°`bЗЙя~ъя   Leonard Fine:Vereda Rosada iMac:Desktop Folder:Houses without cellars   ДhДШ■╞ho(.       @АььмTўьь @тэ@@GРTimes New Roman5РАSymbol3Р Arial3РTimes"qИ╨hзЭcFзЭcF!е└┤┤А207У  1 Leonard Fine Leonard Fine■  рЕЯЄ∙OhлС+'│┘0`ИРЬи└╠▄ Ї  ( 4@HPX'1ss Leonard FineWoeonNormal  Leonard FineWo1onMicrosoft Word 8.0d@@▓2Й╤╧┴@▓2Й╤╧┴■  ╒═╒Ь.УЧ+,∙о0Ё hpДМФЬ дм┤╝ ─ ╥' Chemistryм 1 Title■    ■   ■    ■   ¤   #■   ■   ■                                                                                                                                                                                                                                                                                                                                                                           Root Entry         └F╔ЁщЦ╧┴%А1Table             WordDocument        SummaryInformation(    DocumentSummaryInformation8            CompObj    XObjectPool            ╔ЁщЦ╧┴╔ЁщЦ╧┴            ■                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           ■      └FMicrosoft Word Document■   NB6WWord.Document.8
