## Ideal gas

$w=-P\Delta V$
and
$w=-\int_{V_{1}}^{V_{2}}PdV=-nRTln\frac{V_{2}}{V_{1}}$

### Ideal gas

What should we be thinking about when we come across "ideal gas?"

### Re: Ideal gas

The term "Ideal gas" is often used to describe the Ideal Gas Law PV=nRT, which describes the relationship between pressure, volume, temperature, and the number of moles of a gas. It's also used to transform equations -- for example, $\Delta H=\Delta U+P\Delta V$ can be rewritten as $\Delta H=\Delta U+nR\Delta T$

### Re: Ideal gas

You should know that an ideal gas will follow the equation, PV=nRT, but also that it is a hypothetical gas whose molecules occupy negligible space and have no interactions. It is because of this that they will obey gas laws always.

### Re: Ideal gas

An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly elastic and in which there are no intermolecular attractive forces. The molecules of the gas can collide with one another, but there are no forces that creates an interaction between the gases.
