Question

Which of the following actions can result in decreasing the pressure of a gas inside a sealed container?

increasing the collision rate between particles

increasing the speed at which the gas particles move

decreasing the collision rate between particles

decreasing the speed at which the gas particles move

Answer 1

I think it can be either c or d. What do you think?

Answer 2

both
decreasing the collision rate between particles

decreasing the speed at which the gas particles move
are function of temperature and by decreasing the temperature you lower the pressure, need more clearification?

Answer 3

Increasing the volume would decrease pressure- not one of the choices but think about it.... A bigger container would reduce collision rate- also more heat more activity so decreasing the speed (by taking away or not adding heat) so, yeah... C & d
