I would like to ask if the nuclear and sub nuclear particles react to heat energy supplied to them. For example the quark triads in protons and neutrons?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Thermal energy affects condensed matter, molecules, atoms, and nuclei by exciting atomic transitions with energies of roughly $E=kT$ and below. At room temperature $T=300\,\rm K$, $kT = 25\,\rm meV$ you mostly excite vibrational states in solids, whence the expression "heat is jiggling atoms." At room temperature you can generally make molecules rotate, but not vibrate. I don't have vibrational energies at hand, but you start to make electronic excitations in atoms when you get $kT \approx 1\,\rm eV$, corresponding to $T\approx 12\,000\,\rm K$. Since molecules are held together by electronic interactions, this is the sort of temperature where you can reliably dissociate molecules and you expect to find most atoms not in the ground state.
Generally the first excited state in a nucleus is a couple of MeV above the ground state. So from the perspective of a nucleus any temperature below hundreds of millions of kelvin is "absolute zero," in the sense that you are astoundingly unlikely to have a thermal excitation drive the nucleus away from the ground state. Ordinary temperatures do not have enough energy to thermally excite nuclei.
With quarks bound into nucleons the situation is more extreme. The "first excited state" of the nucleon is the $\Delta$ baryon with mass around 1200 MeV. You won't find thermally-produced $\Delta$s until $kT$ approaches 200 MeV.
Ordinarily you can't talk about temperature unless you are pretty close to a thermal equilibrium; by definition, almost, all the nuclear reactions we observe are far from equilibrium. However, "temperature" turns out to be a pretty good way to describe the energy density in a strongly interacting fluid like the quark-gluon plasma, which was the state of matter for the first minute or so after the Big Bang.
