Chapter 3, Problem 1Q
Interpretation Introduction

Interpretation:

The effect of the poor circulation of the bath liquid on the melting point should be determined.

Concept introduction:

Temperature at which an element changes from the solid state to the liquid state is known as melting point or sometimes liquefaction point. At the melting point, both solid and liquid phase coexist in equilibrium. It depends on the pressure and is normally defined at the standard pressure (1atm).

Answer to Problem 1Q

The measured melting point will be inaccurate as compared to its actual value.

Explanation of Solution

The most important factor in the determination of the melting point is the rate of heating. The rise in temperature should not be greater than 1°C per minute. The bath liquid is to be heated and the heat obtained is transferred to the sample equally. But if the liquid has poor circulation, it will not heat up the sample equally and therefore the measured value of the melting point would be inaccurate. Slow heating and good circulation of the bath liquid results in the thermal equilibrium of the system.
