light

How do

 

I have a question about physics and want to know if there are any elements thatdo not go thru gas solid liquid.

 

 

 

And this is just a question because I am going to talk about light and protonsin the sense of water.

 

 

so 1

 

water at rest is liquid

 

light at rest is a gas-ish

 

 

 

2

 

if at speed of light and observing light, due to speed of both equal- doeslight faze to liquid as speed increases does it solidify<br style="mso-special-character: line-break;"><br style="mso-special-character: line-break;">

Umm, there are plenty of chemicals (CO2 comes to mind) that sublime, or go directly from solid to gas. I'm sure some pure elements do, too. Unfortunately I can't remember which ones off of the top of my head.

 

With regards to the light stuff. I don't really understand what you're talking about.

Light isn't really gas-like, and it certainly never turns into a solid or a liquid.

In some circumstances you can get light turning into matter though

Actually you can treat some collections of photons as a gas

The most common example of a photon gas in equilibrium is black body radiation

 

but I've never heard of a model where they would act like a liquid or a solid

If I remember my school chemistry I think Iodine sublimes at rtp. And I am really struggling here - but don't most things sublime at some temperature and pressure (lower pressure than the triple point)
