変へん化か
変化 is a general term for change or variation, while 変成 emphasizes a complete transformation of form or nature, often in a technical sense.
変へん態たい
変態 specifically refers to biological metamorphosis (e.g., insect development) and can also mean 'pervert' in colloquial use, whereas 変成 is a broader term for transformation.

Compound of 変 (hen, 'change') and 成 (sei, 'become'). The exact historical derivation is uncertain, but the word is used in modern technical contexts.
