Question

If a solid piece of naphthalene is heated and remains at 80 degrees C until is is completely melted, you know that 80 is the what?

Answer 1

If a solid piece of naphthalene is heated and remains at 80 degrees Celsius until it is completely melted, you know that 80 degrees Celsius is the melting point of the solid naphthalene. This is the maximum temperature at which the chromium is in its solid form.

Answer 2

Answer: The given temperature is known as melting point of naphthalene.

Explanation:

Melting point is defined as the temperature at which solid gets converted to liquid.

The temperature remains constant until all the solid has been converted to liquid. At this temperature, solid state and liquid state are present at equilibrium.

$\text{Solid state}\rightleftharpoons \text{Liquid state}$

We are given:

A solid piece of naphthalene is heated till 80°C until all the solid is melted.

Hence, the given temperature is known as melting point of naphthalene.
