Energy from combustion of element

Click For Summary
SUMMARY

The discussion centers on calculating the energy released from the combustion of tungsten when exposed to oxygen, specifically in the context of a broken lightbulb. The suggested method for measuring this energy involves calorimetry, where a beaker of water is placed near the lightbulb to capture the heat released during combustion. By measuring the temperature change of the water and the amount used, one can determine the calories produced. This method, while potentially effective, may have limitations in accuracy.

PREREQUISITES
  • Basic understanding of calorimetry
  • Knowledge of combustion reactions
  • Familiarity with temperature measurement techniques
  • Concept of specific heat capacity
NEXT STEPS
  • Research calorimetry techniques for accurate energy measurement
  • Study combustion reactions of metals, focusing on tungsten
  • Learn about specific heat capacity and its applications in thermal calculations
  • Explore safety measures when working with combustible materials
USEFUL FOR

This discussion is beneficial for chemistry students, educators, and anyone interested in thermodynamics and energy calculations related to combustion processes.

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 .
