                                                                    热的良导体和不良导体

        不同的物体传导热的本领是不同的，人们把善于传导热的物体叫做热的良导体，把不善于传导热的物体叫做热的不良导体，固体中的金属是热的良导体，其他的固体大都是热的不良导体，如石头、陶瓷、玻璃、木头、皮革、棉花等，我们用来烧饭、烧菜的锅都是用善于传导热的金属制成的，目的就是让热尽快地传给待加热的食物．冬季人们穿棉衣、毛衣或羽绒服，正是因为这类东西都是热的不良导体，可以保存身体散发出的热量，达到保暖的目的，

问题：  

日常生活中哪些物体是热的良导体？哪些物体是热的不良导体？跟同学们交流一下，看谁举的例子最多.
