Why the electrodes in a cell must be made from different materials

Physics

It is because if electrodes are made from same material, there will be no flow of charges. The electrodes are such chosen so that one electrode is willing to lose electrons and other is willing to gain electrons. The choice of material is accordingly, one electrode should be made form an electro-negative material and the other should be made from a electro-positive material. This makes the charges to flow between the two electrodes.

Unlike a ball, an atom doesn't have a fixed radius. The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance... Does that answer your question?

Calculate the value of δs when 64.0 g of ga(l) solidifies at 29.8 ∘c.
frez [133]
The variation of entropy of a substance is given by
\delta S =  \frac{\delta Q}{T} (1)
where
\delta Q is the heat exchanged in the process
T is the absolute temperature at which the transformation occurs.

The process in the problem is the solidification of the liquid Gallium, which releases an amount of heat equal to:
\delta Q = m L_f
where m is the mass of the substance and L_f = 80.1 J/g is the latent heat of fusion of Gallium. Using m=64.0 g, we find
\delta Q= m L_f = (64.0 g)(80.1 J/g)=-5126.4 J
where the negative sign means the Gallium is releasing heat to the environment.

Now we can use equation (1) to find the variation of entropy, but first we need to convert the temperature into Kelvin:
T=29.8^{\circ} + 273.15 = 302.95 K

And so the variation of entropy is 
\delta S =  \frac{\delta Q}{T}= \frac{-5126.4 J}{302.95 K}=-16.92 J
and the negative sign means the entropy in the process is decreasing.
