If cool air is more dense and sinks, what effect do you think that would have on air pressure on the ground? If warm air is less dense and rises, what effect do you think that has on air pressure on the ground?
there are 2 questions

Greater activity of the heated molecules increases the spacing between neighboring molecules and thus reduces air density. The decreasing air density then lowers the pressure exerted by the air. Warm air is thus lighter (less dense) than cold air and consequently exerts less pressure.

c, they united with once

well first we can compare on what the slave masters ate and what the slaves ate well the masters ate fancy great food like chicken rice mash potatose and stuff like that and slaves ate well food that your not suppost to eat like the weird parts of turkey and chicken and slaves master chilled beat and eat and slaves work get beat and get little of sleep there you go
