11.7 atmospheric pressure

Question 1

pressure (defintion)

Answer 1

the force per unit area, it is a physical property of all states of matter and is measured in pascals (pa) or kilopascals (kpa)

the si unit is pa (but usually need to do in kpa

Question 2

pressure is proptional to ?

Answer 2

force: it is directly related to the size of force (greater the force greater the pressure

Question 3

pressure is inversely related to ?

Answer 3

area. bigger the area the less pressure

Question 4

atmospheretic pressure defintion

Answer 4

force per unit area exerted by air of all objects

Question 5

standard pressure definition

Answer 5

sea level force exerted is 101.325kpa

Question 6

stp = ?

Answer 6

standard temp and pressure, 0 degrees at sea level which is 101.325 kPA

Question 7

satp

Answer 7

standard amvirent temp and pressure, 25degrees at 100kpa

Question 8

temperature is ..?

Answer 8

the measurement of kinetic movement

Question 9

stp pressure values in all units

Answer 9

101.325 kPa = 760 Toor = 760 mm hg = 14.7 psi = 1 atm

Question 10

where is the density of the atmospheric gas greatest at?

Answer 10

at sea level (and density of the air decreases as altitude increases)

Question 11

what is live high train low

Answer 11

the density of air decreases as the altitude increases, therefore there is less oxygen (a lower density of oxygen)

21% of the air is still oxygen its just there is less air, body compensates for less oxygen by making more red blood cells to carry the oxygrn sround more
