TRUQUE DA FUMAÇA SAINDO DOS DEDOS Sabia que se retirarmos o fósforo da caixinha de fósforo (aquela parte onde riscamos o palitinho) e queimarmos em uma cerâmica gelada, o que sobra é fósforo branco? Essa “lixa” é fósforo vermelho puro, quando queimada em uma cerâmica gelada o resíduo que fica condensado é fósforo branco, e com o atrito das mãos gera calor, que formam minúsculas partículas de óxido de fósforo que se dissipam como fumaça. #ciência #curiosidades #quimica #física
