根据Drop nuts into jar to give it more weight(把金属螺母放进罐子里,使它更重。)可知,使用金属螺母的目的是让罐子更重。故选B。(4)推理判断题。根据Colored water comes streaming(动) up out of the jar and flows around in the pot.Hot water is less dense (密度大的)than cold(it weighs less...
A. denser than cold air B. less dense than cold air C. the same density as cold air D. not related to density 相关知识点: 试题来源: 解析 B。热空气上升是因为它的密度比冷空气小,B 选项正确。A 选项热空气密度大于是错误的。C 选项密度相同不符合实际。D 选项说与密度无关是错误的。反...
The Mpemba effect is the name given to the assertion that it is quicker to cool water to a given temperature when the initial temperature is higher. This assertion seems counter-intuitive and yet references to the effect go back at least to the writings of Aristotle. Indeed, at first thought...
