Please answer & explain 22-25
22. Pressure is created when a gas is compressed and the temperature is decreased proportionally b) gas particles collide with the sides of their container more gas particles are added and the volume is increased proportionally gas particles are removed and the volume stays the same 23. because In response to Boyle's law, the pressure of a gas increases as the volume a) decreases; the gas particles strike the walls of the container more often...

3. Which of the following statements best explains why nitrogen gas at STP is less dense than Xe Has at STP? a) Because Xe is a noble gas, there is less tendency for the Xe atoms to repel one another, so they pack more densely in the gas state. b) Xe atoms have a higher mass than N2 molecules, Because both gases at STP have the same number of molecules per unit volume, the Xe gas must be denser, c)...
