How do I measure surface temperature with a thermocouple on a filament bulb?

AI Thread Summary
Measuring the surface temperature of a filament bulb with a thermocouple is ineffective using contact methods due to the low thermal mass of the filament. Contact with the sensor will cause the filament to equalize its temperature with the probe, leading to inaccurate readings. For accurate measurements, non-contact methods such as infrared thermometers are recommended. Repeated questions on the same topic should be avoided to maintain clarity in discussions. Understanding the limitations of contact temperature measurement is crucial for accurate results.

Can some 1 pls tell me how to measure the surface temperature of the filament bulb with a thermocople, do you put the sensor on the surface or what. As i am new to this can u pls help. Thanks you

You will not be able to get a meaningful temperature of a filament with a contact method. The thermal mass of a filament is very low, contact with any object will cause the filament to equalize in temperature with the probe, thus you will not measure the correct temperature.

See my response to this same question in your previous post. Please do not double post.
 

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
