How can the fugacity of this state equation:
$p V / (n R T) = 1 + [b - a / (R T)] p / (R T)$
be calculated?

I am evaluating the partition function of a system of particles and incurred in sums like
$S (a) = \sum_{k = 0}^{\infty} (2 k + 1)^{\frac{κ}{2}} e^{- (2 k + 1) a}$

A substance at 200-degree Celsius is given some amount of heat to raise its temperature by one degree Celsius and the same substance when at -200 degrees Celsius is given some amount of heat to increase its temperature to -199 degrees Celsius. Is the amount of heat required for both the processes same?

Scientists say that it is impossible to reach a temperature of zero kelvin, because the atoms will stop moving, and the volume of the substance will become zero, But we have reached the pico kelvin temperature, which is almost zero, and there is no difference between it and zero, so why do they say it is impossible? and The laws of physics still work at picokelvin.

Is there a clear analogy here between volume and entropy? Looking at: $\frac{d Q}{T} = d S, \frac{d W}{P} = d V$

Is there a name for this sort of thermo relationship?
$H_{v a p / s u b / c o n d} (T^{'}) - H_{v a p / s u b / c o n d} (T) = \int_{T}^{T^{'}} Δ C_{p, m} d T$

Is n=1 (degrees of freedom) for monatomic?

Thermodynamics is the study of energy and how it is transferred, transformed and even conserved. It's an essential branch of physics, and it's used to understand how energy works in many different fields, from manufacturing to engineering to astronomy. It's also used to understand and predict energy-related changes in the environment. Thermodynamics can help us understand how heating and cooling systems work, why the Earth's atmosphere is constantly changing, and even the formation of stars and galaxies. It's a fascinating field, and one that offers a great deal of insight into the world around us.
