Question

Define Melting Point and Freezing point .​

Answer 1

Answer:

Melting Point: The temperature at which a substance changes its state from solid to liquid is called its melting point.

Freezing Point: The temperature at which a substance changes its state from liquid to solid ic called its freezing point.

The melting as well as the freezing point of water is 0°C.

Define Melting Point and Freezing point .

$\huge\bold{\color{purple}{\fbox{ANSWER}}}$

$\huge\bold{\red{{Melting~Point}}}$

SIMPLE DEFINITION :

The temperature at which a substance will melt is called melting point.

SCIENTIFIC DEFINITION :

The melting point of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium.

The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.

$\huge\bold{\red{{Freezing~Point}}}$

SIMPLE DEFINITION :

The temperature at which a liquid turns into a solid when cooled is called freezing point .

SCIENTIFIC DEFINITION :

The Freezing point is the temperature of a liquid at which it changes its state from liquid to solid at atmospheric pressure.

MOST IMPORTANT DEFINITION :

A more specific definition of freezing point is the temperature at which solid and liquid phases coexist in equilibrium.

The normal freezing point is the temperature at which a substance melts (or freezes) at one atmosphere (760 torr = 760 mm Hg = 14.7 psi = 101.3 kPa) of pressure.
