Answer:

hlo buddy

Explanation:

1. The temperature at which a given solid will melt.

2.. The temperature at which of liquid equals at the pressure and surrounding the liquid.

3.latent heat of vapourization is defined as heat required to change one mole of liquid at its boiling point under standard atmospheric pressure

4.

Answer 2

Answer:

$\huge\tt{Melting\:point}$

The melting point of a substance is defined as the temperature at which a substance changes from solid phase to liquid phase; that is, undergoes fusion. 

_______________________

$\huge\tt{boiling\:point}$

The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid.

_______________________

$\huge\tt{Latent\:heat\:of\:fusion}$

The amount of heat required to change 1 g of a substance at the temperature of its melting point from the solid to the liquid state without changing temperature.

_______________________

$\huge\tt{Latent\:heat\:of\:vapourisation}$

Latent heat of vapourisation is a physical property of a substance. When a material in liquid state is given energy, it changes its phase from liquid to vapour without change in temperature, the energy absorbed in the process is called latent heat of vaporization.

_______________________

$\huge\tt{Sublimation}$

Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.

_______________________

$\huge\tt{boiling\:of\:vapourisation}$

Vaporization (or vapourisation) of an element or compound is a phase transition from the liquid phase to vapor. ... The term Boiling is defined as the process in which the liquid phase changes to gaseous phase at a constant temperature is called as Boiling.

_______________________

$\huge\tt{melting\:or\:fusion}$

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.

_______________________

$\huge\tt{Diffusion}$

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.
