(a)Thermal expansion of solids,liquids and gases 固体,液体和气体的热膨胀。 1-describe qualitatively the thermal expansion of solids,liquids and gases 定性的描述固体,液体和气体的热膨胀。 2-identify and explain some of the everyday applications and consequences of thermal expansion 描述和解释一些生活...
液体(liquids)的特性如下:液体需要装在特有形状的容器中;液体可以改变成不同的形状,但体积(volume)不会发生改变;液体可以被倾倒。 关于气体(gases),你了解哪些知识呢?老师先让孩子自己进行思考并尝试表述。气体也是非常小的物质单位,它们的属性也非常多...
To do well in GCSE physics, students need to understand the kinetic theory of matter. This explains how the properties of solids, liquids and gases are affected by the movement of their particles due to heat or thermal energy. Have a go at this quiz and
