lol these answer choices are so poorly stated

anonymous · Answer

but I think what answer choice your teacher is looking for is vapor pressure

anonymous · Answer

b/c think of the atmospheric pressure as a lid/container, and it's keeping the vapor pressure of the solid at a low amount

anonymous · Answer

if the atmospheric pressure decreases, your lid isn't strong enough to push down on the solid's vapor pressure (which was keeping the solid as..well..a solid), so your solid just turns all into vapor

anonymous · Answer

which is called sublimation (directly from solid to gas)
