When using a thermometer...
possibly an equilibrium of all particles evenly distributed between the target of measurement and the thermometer. All these particles contain KE in a 2D plane. When confined to a long tube, all such particles contributes to the extend of the remaining free dimension. More vibration energy results in a greater length along the tube.
Using thermal Imaging...
temperature photons where the time dimension along which the wave that makes up the temperature particles have light speed, are replaced with a space dimension, \(x_2\). These photons are enable to eject temperature particles analogous to photoelectric effect. With reference to thermal imaging, these photons are in the infra red spectrum. But how do we know in the first place, we are capturing temperature related information consistently?
Using our hands...
oscillating energy along \(t_c\) of all particles affects chemical changes. As long as the particles are enable to affect biochemical changes that we register as heat, we will detect them as hot.
