Zeroth Law of Thermodynamics is Related to Temperature
The zeroth law of thermodynamics states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. It is called the zeroth law because it was formulated after the first and second laws of thermodynamics. The zeroth law is related to temperature because it establishes the concept of temperature as a property that determines thermal equilibrium.
Entropy is Related to First Law of Thermodynamics
The first law of thermodynamics is the law of conservation of energy. It states that energy cannot be created or destroyed, only converted from one form to another. Entropy is related to the first law of thermodynamics because it is a measure of the amount of energy that is no longer available to do work. When energy is converted from one form to another, some of it is lost as heat, and the entropy of the system increases.
Internal Energy of an Ideal Gas is a Function of Temperature and Pressure
The internal energy of an ideal gas is the total kinetic and potential energy of its molecules. It is related to temperature and pressure because the kinetic energy of the gas molecules is proportional to the temperature, and the potential energy is proportional to the pressure.
Van der Waals Equation is Related to an Ideal Gas
The Van der Waals equation is a modification of the ideal gas law that takes into account the intermolecular forces between gas molecules. It is related to an ideal gas because it is an attempt to make the ideal gas law more accurate by accounting for the deviations from ideal behavior that occur at high pressures and low temperatures.
Therefore, the correct statement among the given options is 1 only, as the zeroth law of thermodynamics is related to temperature.
