Question

Explain piezoelectricity. Discuss kinds of information available from thermogravimetric analysis. Go to https://lapom.unt.edu and there to Resources on Education. See computer animations of materials behavior. Why simulations ? What did you learn ? Explain the use of the phenomenon of flocculation. As an example, one puts a flocculating agent into a suspension such as that of manganese ore in water. What happens ? What objectives can be accomplished ? Why are long chain polymers good flocculating agents ? Discuss various applications of the phenomenon of drag reduction.

Explanation / Answer

1) piezoelectric -:when some material are subjected to mechanical stress (like compressed , twisted or distorted) this stress dependent change in polarization manifests potential difference across the material is called piezoelectric effect.
