What is an ideal gas

Solution Step 1 of 2 In case of ideal gas, the interaction between the atoms or molecules inside the gas are negligible and the atom or molecule is considered to be a hard sphere, whose size is very small and negligible compared to the total volume of the gas. Such gases obeys the gas laws; Charles's law and Boyle’s law exactly at all temperatures and pressures. Such kind of gases are known as ideal gas.
