Solid have the unique shape and low temperature, plasma have not unique shape and high velocity and both show electrical conductivity.
Matter is divided into 4 states as solid, liquid, gas and plasma according to the arrangement of atoms present in that.
In the solid state all particles are connected rigidly with each other, and show very less movement that's why maintain a unique structure. They have low temperature as it helps to maintain the rigidity and it also conducts electricity because of the presence of electrons in the constitute atoms.
This is the 4th state of matter in which positively and negatively charged particles are present, these particles are held together by the weak force that's why they show good velocity, and do not maintain a unique shape. Plasma also shows the electric conductivity.
Hence, both state will conduct electricity and show different characteristics.
