Salut ! 

En fait ici t'as un changement d'état : Glaçon (solide) que tu fais fondre en Eau (Liquide)

 

La formule correspondante n'est donc pas la bonne, il faut utiliser la formule de la chaleur latente.

Je te mets le screen du tutorat !

 

➢  Chaleur latente : changement d’état
Q= mLT avec L, chaleur latente massique, propre à un changement d’état
