According to the ideal gas law, pressure is directly proportional to the number of moles of gas when temperature and volume are constant. The first statement is incorrect because pressure is inversely proportional to volume (Boyle's Law), and the third statement is incorrect because volume is directly proportional to temperature (Charles's Law).
