Which of the following is a physical property of copper?A. Ductile, can be drawn into a wireB. Liquid at room temperatureC. Readily reacts with water to form an acidD. Readily reacts with oxygen
If you think about these you can work it out. A penny is made of copper. Is a penny liquid at room temperature? No. Does a penny react with water to form an acid? No. Does a penny react with oxygen (the air)? Yes, but over a long time (old pennies are tarnished which is oxidation). The first one (ductile) doesn't have much to do with a penny - but have you ever seen the inside of an extension cord or speaker wire or any electrical wires? Its copper. So it must be able to be drawn into a wire.
