锟斤拷锟斤拷Annealing

锟斤拷锟斤拷Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly, for example by dipping (锟斤拷) it in water, it will be very hard but also very brittle-that is, it will break easily. Metal that has been annealed is soft but does not break as easily. It is possible to make metal as hard or as soft as it is wished, by annealing it. The metal is heated, and allowed to cool slowly for a certain length of time. The longer the heated metal takes to cool slowly, the softer it becomes. Annealing can also be used on other material, such as glass.

锟斤拷锟斤拷1. Why do people put hot metal in water?

锟斤拷锟斤拷A. To make it hard. B. To make it soft.

锟斤拷锟斤拷C. To make it cool. D. To make it brittle.

锟斤拷锟斤拷2. In annealing, the required hardness of metal depends on __.

锟斤拷锟斤拷A. the quantity of water used B. the temperature of the metal

锟斤拷锟斤拷C. the softness of the metal D. the timing of the operation

锟斤拷锟斤拷3. As suggested by the text, how can glass be made less brittle?
