Extensive bodies have the property of weighing less when they
are in water than when they are in air, which you notice when you
swim, for example. For this reason, even heavy container ships can
swim, although a small pebble immediately sinks. In this
experiment, weare dealing ...
Density is known as a characteristic material property of solid and liquid matter. A gas such as air, which, from the perspective of physics, is matter too, also has this property of course. In the experiment, a sphere of known volume is filled with air and then weighed. The result ...
Hydrostatic pressure in a fluid depends only on the height and not on the shape of the container.
Different containers can be placed on the Pascal's vase apparatus. In each case, the pressure on the bottom is transferred to a pointer.
The buoyancy force is equal to the force of the weight of the
liquid displaced: This experiment uses the archimedean principle to
determine to which extent the buoyancy depends on the mass and
volume of a body and the density of the liquid, using everday
objects (cola, ...
The density of water and glycerol is determined as a function of
temperature using the Mohr balance.
The density of water and glycerol is measured in 1 to 2 °C steps
over a temperature range from 0 to 20 °C, then in larger steps up
to 50 °C.
A vessel containing liquid is rotated about an axis. The liquid surface forms a paraboloid of rotation, the parameters of which will be determined as a function of the angular velocity.
On the rotating liquid surface, the following are determined:
The viscosity of liquids can be determined with a rotation viscometer, in which a motor with variable rotation speed drives a cylinder immersed in the liquid to be investigated with a spiral spring. The viscosity of the liquid generates a moment of rotation at the cylinder which can be ...
Due to internal friction among their particles, liquids and
gases have different viscosities. The viscosity, a function of the
substance's structure and its temperature, can be experimentally
determined, for example, by measuring the rate of fall of a ball in
a tube filled with ...
The force is measured on a ring shortly before a liquid film tears using a torsion meter. The surface tension is calculated from the diameter of the ring and the tear-off force.
The cohesive forces in a liquid generate tension on its surface,
the so-called surface tension. A metal ring that is plunged into a
liquid is withdrawn from the liquid. At a certain tensile force,
the liquid film will be disrupted from the ring. Based on the
tensile force and ...
The force exerted on a measuring ring shortly before the liquid film is torn away is determined with a force meter. The surface tension is calculated from the diameter of the ring and the tearing force.
Determination of the surface tension of water and other liquids.
