Question

define Enthaply of fusion and vaporization​

Answer 1

Heat of fusion is the energy needed for one gram of a solid to melt without any change in temperature. Heat of vaporization is the energy needed for one gram of a liquid to vaporize (boil) without a change in pressure. ... So the heat of fusion is an endothermic process it requires heat so the delta h is positive.

Answer 2

Answer:

Hi,

Explanation:

$\huge\boxed{\mathcal\green{Answer:-}}$

1. Enthaply of Fusion :- Enthalpy of fusion is the energy required for a specific quantity of the substance to change its state from solid to liquid at constant pressure. Here, we generally provide energy by heat. -Enthalpy of fusion is also known as latent heat of fusion.

2. Vaporization :- When a liquid changes form into a gas, the process is called vaporization. You can watch vaporization when you boil a pot of water. Vaporization happens in two ways: evaporation and boiling. Evaporation occurs when sunlight shines on water until it changes to vapor and rises into the air.
