AI Thread Summary
It is possible to separate heat from light using devices like cold mirrors, which reflect visible light while allowing infrared radiation to pass through. Heat is not a substance but rather energy transferred through electromagnetic radiation, such as that from a fire. The discussion clarifies that the original question was about splitting visible light from the portion of electromagnetic radiation that causes heating. Cold mirrors are identified as a solution for this separation. Overall, the conversation emphasizes the distinction between light and heat in terms of energy transfer.

Hello

The question is: it possible to separate heat from light?

I'm not sure I know what you mean, but windows transmit visible light while blocking IR.
 
Uh ... infrared is electromagnetic radiation. Just like light.

Yes. One way is called a cold mirror. It's a filter that reflects light but passes heat. You can buy them.
 
You have to be careful by what you mean when you say "heat". Heat is not a substance that is transferred between different objects. For example, when you stand near a fire, the electromagnetic radiation from the flames interact with your body and give up energy to you. This is one form of "heating". The light does not also contain some substance called "heat" that it delivers to you.

You also receive energy from the convection, but that's not what you're asking about.
 
Sorry for not being clear ,from your answers i understood i should've ask about splitting
visible light and portion of electromagnetic radiation that is responsible for heating objects.
Cold mirrors seems to be exactly what i was wondering about.
Thank you for replies.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
