Answer
A gas which obeys Boyle’s law, Charles’ law and Avogadro’s law for all values of temperature and pressures and which obeys the equation of state PV = nRT under all conditions of temperature and pressure is called an ideal gas.
The pressure of a gas in a closed container increases with an increase in temperature due to the kinetic theory of gases. As temperature rises, gas molecules move faster, leading to more frequent and forceful collisions with the container walls, which raises the pressure.
