According to the Gay-Lussac's Law, the pressure of a gas is directly proportional to its absolute temperature (measured in Kelvin) when the volume is held constant. When the temperature increases from 100°C (373K) to 600°C (873K), the increase in temperature is by a factor of 873/373, which is less than 6. Therefore, the pressure will also increase but by a factor less than 6.
