Questions and Answers

What is the equation for entropy in thermodynamics?

The equation for entropy in thermodynamics is $S = k_{B} \ln \Omega$, where $k_{B}$ is the Boltzmann constant, and $\Omega$ denotes the volume of macrostate in the phase space or otherwise called thermodynamic probability.

What is the first law of thermodynamics for quasi-static and reversible processes?

The first law of thermodynamics for quasi-static and reversible processes is $dU = \delta Q - \delta W$, where $\delta Q$ is the heat supplied to the system and $\delta W$ is the work done by the system.

What is the equation for entropy change in reversible processes?

The equation for entropy change in reversible processes is $dS = \frac{\delta Q}{T}$.

What are the useful results from the Maxwell–Boltzmann distribution for an ideal gas?

Useful results from the Maxwell–Boltzmann distribution for an ideal gas include the implications of the Entropy quantity and are valid for atoms or molecules constituting ideal gases. Signup and view all the answers

What distinguishes matter in the solid state from matter in the liquid state?

Matter in the solid state maintains a fixed volume and shape, with component particles close together and fixed into place, while matter in the liquid state maintains a fixed volume but has a variable shape that adapts to fit its container, with particles still close together but able to move freely Signup and view all the answers

Describe the properties of matter in the gaseous state.

Matter in the gaseous state has both variable volume and shape, adapting to fit its container, with particles neither close together nor fixed in place Signup and view all the answers

What characterizes matter in the plasma state?

Matter in the plasma state has variable volume and shape, and contains neutral atoms as well as a significant number of ions and electrons, both of which can move around freely Signup and view all the answers
