一天,爱动脑筋的小明发现,妈妈在给冻肉解冻时用的是冷水,难道冰在冷水中比在热水中熔化得更快吗?小明带着这个疑问,想和自己的小组成员通过实验来验证。【提出问题】冰在冷水中还是热水中熔化快?【猜想假设】猜想一:冰在热水中比在冷水中熔化快,因为温差大,热传递快,放出的热量多;猜想二:冰在冷水中比在热水中熔化快,因为生活中常用冷水来 One day, Xiao Ming, a mother of mine, found that her mother used cold water when thawing frozen meat, did ice melt faster in cold water than in hot water? Xiaoming took this question and wanted to pass with her own team members Experiment to verify. 【Ask questions】 Ice in hot water or cold water melts fast? [Assumptions] Assumptions 1: Ice in hot water melts faster than in cold water, because the temperature difference, heat transfer fast release of more heat; guess two: Ice melts faster in cold water than in hot water because cold water is commonly used in life
