Help true or false gas problem?

True of false... at a constant amount and pressure, as the temperature of a sample of gas particles in a container is increased, the volume increases to maintain the same amount of collisions with the walls of the container.Help true or false gas problem?
Actually, it's false. The question is badly worded; ';amount'; isn't well defined here. But if we are talking about number of collisions per second, then with a temperature and volume increase (but a constant pressure), what is happening is that there are fewer collisions per second with the walls, but each is more energetic. It is the product of these two items that gives the pressure.Help true or false gas problem?
True, Charles's Law states that for a fixed amount of gas at constant pressure the volume is directly proportional to the temperature.
