Chapter 3, Problem 11STP

Interpretation Introduction

Interpretation:

The melting point of a gas $-295°c$ reports by a student, this would be an incorrect claim explained it.

Concept introduction:

The temperature at which solid state changes into a liquid state, known as Melting point. This phase transfer process maintains the equilibrium.

Answer to Problem 11STP

This statement is incorrect because gas can be liquefied, so the melting point of gas cannot be measured at $-295°c$.

Explanation of Solution

$0K$ Kelvin or $-273°c$ is the lowest temperature which is termed as absolute zero, so the $-295°c$ temperature is not measured. The gaseous state the particles move freely. But by applying pressure or decreasing the temperature the decreasing in the intermolecular space of particles. So, gas doesn't melt.

The value of $-295°c$ is equals to $-22K$. $0K$ is absolute zero and no temp can be lower than this, so, this answer does not make any sense

Conclusion

The melting point is considered for the solid particle, for gas the melting point cannot be measurable. So, the givenstatement is incorrect.
