1.
A force of 40 N acts perpendicularly on an area of 0.20 m2. The pressure is
200 Pa
8 Pa
0.005 Pa
800 Pa
2.
The pressure in a liquid at rest increases with depth because
molecules are heavier at depth
the liquid above must be supported
the liquid is hotter
gravity is stronger at depth
3.
A gas is at 2.0 × 105 Pa gauge pressure with atmospheric pressure 1.0 × 105 Pa. The absolute pressure is
1.0 × 105 Pa
2.0 × 105 Pa
3.0 × 105 Pa
0.5 × 105 Pa
4.
According to kinetic theory, gas pressure arises from
repulsion between molecules
the weight of the gas
the friction between molecules
the change in momentum of molecules colliding with the walls
5.
Pressure at 10 m depth in sea water (ρ = 1030 kg m−3) due to the water alone is approximately
1.0 × 103 Pa
1.0 × 105 Pa
1.0 × 104 Pa
2.0 × 105 Pa
6.
A graph of total pressure against depth in a liquid is a straight line. Its gradient equals
p0
ρ
ρg
g/ρ
