Why was it better to build skyscrapers with steel instead of iron?

Because steel has a high cost/strength density. In other words, its cheap to use when you take into account that you don't have to use as much of it. And steel has many favorable properties, unlike wood, steel will normally give some indication that it is going to fail (crack, deformation, etc.) where as wood will just break. This is good because it gives you a chance to fix the problem before it becomes life threatening.

Which is hotter an electric fire or a light bulb?

An electric fire has a wattage of between 1 and 3 kw depending on the model - a light bulb can be anywhere between 40 and 120w.So an electric fire is a lot hotter.Another AnswerIf, by 'hotter', are referring to temperature, then lamps operate at a far higher temperature than an electric fire (white hot vs red hot!). If, by hotter, you are referring to the amount of energy consumed, then electric fires win!
