Which of the following is true about a 0.200 mol sample of nitrogen gas and a 0.200 mol sample of argon gas that are at 1.20 atm and an initial temperature 55.0°C when the temperature changes to 400 K? Assume constant volume for the container under both of these temperature conditions. The density of both gases will increase. There will be more collisions between the gas molecules and the pressure in the container will decrease. None of these choices is...
