Energy from combustion of element

AI Thread Summary
The discussion centers on the combustion of tungsten in a lightbulb when exposed to oxygen. To measure the energy released during this process, calorimetry can be used by placing a beaker of water near the bulb and recording the temperature change as the tungsten combusts. The amount of water and the temperature increase can help calculate the energy in calories. However, the effectiveness of this method is questioned, suggesting it may not yield accurate results. The potential for fire is also a concern when oxygen interacts with the heated filament.

So I was reading about lightbulbs... and if I broke the bulb so that oxygen came onto the heated filament, I understand that the tungsten would combust. But how would I figure out how much energy would be given off? Would this cause a fire?

I have no chemistry training so be gentle!

well you could use calorimetry , you could put a beaker of water near the light bulb before it combusts , and not very much water in the beaker and a calorie is the amount of heat energy required to raise 1 gram of water 1 degree Kelvin , then you could measure how much water you put in the beaker and the temperature change in the water and then you would know how many calories were given off . This may not work that well . But its all i could think of .
