AI Thread Summary
The discussion centers on the observation that the top of a bulb may be hotter than the sides, but participants emphasize the lack of sufficient information to provide a definitive answer. A detailed description of the apparatus, methods, and goals is necessary for meaningful assistance. One user suggests that the temperature difference could be related to tungsten filament evaporation affecting light absorption over time. The inquiry also includes a request for help in investigating the relationship between power and temperature, questioning whether temperature decreases as power increases. Overall, the conversation highlights the need for more context to address the temperature issue effectively.

CAn you tell me why will the temperature of the surface will be hotter at the top on the blub rathen than on the side?
thank you

No, we cannot tell you why the top might be hotter then the sides. Why? Simply because you have not provided enough information to even guess. If you want meaningful help with this project you will need to post a detailed discription of your appratus, your methods and your goals.


Further, I would appreciate it if you would use a single thread rather then starting a new one for each question.

Thanks,

alright i am sorry

Is it because "The tungsten filament evaporates more rapidly as the temperature of the filament goes up. The evaporated tungsten particles tend to deposit on the glass envelope, causing over time, an increase in light absorption. Eventually, the filament material will evaporate enough to cause the filament to break, completely ending the life of the lamp."

i am doing an investigation to find the relationship between power and temperature?

need to find the surface temperature, also can u tell me how the graph would look like for the power and temperature. will it be as power increase the temperature decrease?

thanks and i am sorry for the 2 post
