The temperature, proton.

[alpha2cen]

We know proton is made of quarks.

When we come up the temperature continuously the proton is divided into quarks.

How high is the temperature?

[insane_alien]

How high is the temperature?

 

depends on how hot it is

[swansont]

There is no temperature at which a proton will be divided into quarks. Their binding increases with separation, so adding enough energy merely creates quark/antiquark pairs, as mesons, rather than freeing quarks from the nucleus.

[alpha2cen]

But there is a temperature at which quarks and gluons are freely moving in the constrained area.

I mean that temperature.
