DENSITY IN IRREGULAR SHAPES
PRESSURE
pressure = force / area P=F/A
5. I understand how the pressure at a point in a gas or liquid at rest acts equally in all directions
The pressure at a point in a gas or liquid at rest acts equally in all directions and causes a force at right angles to any surface.
- Pressure in a fluid (gas or liquid) is created from the movement of particles (as they collide with a surface)
- In gasses and liquids at rest, the pressure at any point acts equally in all directions. The pressure increases
the depth.
pressure difference: p = h × ρ ×g
INCREASE IN TEMP = INCREASE IN TEMP OF GAS MOLECULES
As you increase the temperature of a gas, the kinetic energy of the gas particles increases and thus their
average speed also increases.
