# When a gas is compressed, its temperature goes up. Why?

Boyles Law – states that for a given mass of gas held at a constant temperature the gas pressure is inversely proportional to the gas volume. The empirical laws that led to the derivation of the ideal gas law were discovered with experiments that changed only 2 state variables of the gas and kept every other one constant. All the possible gas laws that could have been discovered with this kind of setup are: The ideal gas law allows us to calculate the value of the fourth variable for a gaseous sample if we know the values of any three of the four variables (P, V, T, and n). Since it's hard to exactly describe a real gas, people created the concept of an Ideal gas as an approximation that helps us model and predict the behavior of real gases. The term ideal gas refers to a hypothetical gas composed of molecules which follow a few rules: Ideal gas molecules do not attract or repel each other. The ideal gas law is perhaps the best-known equation of state, and admits both a derivation via the kinetic theory of gases and via statistical mechanics. But these are both microscopic theories, and the ideal gas law is a macroscopic equation.

Next lesson. Partial pressure. The law which is of the ideal gas that is PV = nRT that relates the macroscopic properties which are of ideal gases. An ideal gas which we have learnt is a gas in which the particles that do not attract or repel one another and take up no space and have no volume. It is clear, from the previous derivation, that the crucial element needed to obtain the ideal gas equation of state is the absence of interatomic forces.

Undergraduate and graduate physics and chemistry books usually state that combining the gas laws results in the ideal gas law. Leaving the derivation to the students implies that this should be a The Ideal Gas Law Derived Description: Discussion and derivation of the ideal gas law from the equipartition theorem. Then some simple conceptual questions about the ideal gas law.
