As what we learnt last year...When you heat a rod at the end,the particles nearest to it would gain the energy and vibrate faster...Then particles would hit against each other passing the energy from particles to another particles...After a while every particle would receive the energy and would vibrate faster...Therefore you could feel the heat on the other side of the rod...Before the particles vibrate faster,it was already vibrating...(according to what we study)

To proof:How do you know whether the particles are vibrating before it is heated and after
it is heated?
Question:How to proof it...That was what we studied but Proof it is a hard thing...

Does brownian motion makes any sense???

Brownian motion (named after the Scottish botanist Robert Brown) is the seemingly random movement of particles suspended in a fluid (i.e. a liquid or gas) or the mathematical model used to describe such random movements, often called a particle theory.
The mathematical model of Brownian motion has several real-world applications. An often quoted example is stock market fluctuations.
Brownian motion is among the simplest of the continuous-time stochastic (or random) processes, and it is a limit of both simpler and more complicated stochastic processes (see random walk and Donsker's theorem). This universality is closely related to the universality of the normal distribution. In both cases, it is often mathematical convenience rather than the accuracy of the models that motivates their use
