Question

A solid which has definite heat of fusion is
Plastic, CaCl2, glass, soda lime glass​

Answer 1

Answer:

A soild which has definite heat of fusion is Glass.

Answer 2

Answer:

The correct answer is $CaCl_2$.

Explanation:

Apart from $CaCl_2$, rest of them are amorphous solids and they do not possess definite heat of fusion.

$CaCl_2$, being a crystalline solid, possesses a definite heat of fusion.

Calcium chloride :

A salt having the chemical formula $CaCl_2$, calcium chloride is an inorganic substance. At room temperature, it is a white, crystalline solid that is very water soluble.

Crystalline solid :

A solid whose components are arranged in a highly ordered microscopic structure to form an all-pervasive crystal lattice is referred to as a crystal or crystalline solid.

Heat of fusion :

There is a specific amount of energy needed to convert a solid into a liquid. It is known as the heat of fusion.
