Pressure And Density Flashcards
0
Q
Balancing of pressure
A
I’d air is sucked out of a can it crumples as there is no air on the inside to push against the air on the outside
1
Q
Pressure
A
Concentration of weight over a certain area
2
Q
Density
A
The mass of a metre cube of substance
Measured in kg/m^3
g/cm X1000 —> kg/m
3
Q
Brownian motion
A
Random motion of gas and liquid particles is why pressure acts in all directions at one point
4
Q
Temperatures effect on molecules
A
Increase the molecules speed
Faster moving molecules in a container means more collisions
Increases pressure
5
Q
Kelvin
A
-273*C
Proportional to the molecules movement
