compasses have Mineral Oil filled Needle Housings, with steel needles that pivot on a sapphire bearing
The light mineral oil is there to damp the needle (stop the needle swinging too loosely) and it has to withstand freezing (because compasses are used in cold places).
The predominate liquid used inside a filament transformer is mercury. Mercury is used to keep the transformer cool when under heavy use. Mercury is a cheap and long lasting liquid.
The prismatic compass is a type of compass use for survering a land.
M9 paper is used to detect liquid chemical agents such as blister or nerve agents.
A compass is used by various people in different fields to know their location and destination. The most common professions that use a compass are pilots, ship captains and also geographers.
In a DC circuit yes. The compass detects the magnetic field around the wire. Reverse the DC current and the compass will swing 180 degrees from the position is was in.

Yes.
Inside a glow stick, there is a liquid chemical, which could be glowing only once.
The fluid inside a Suunto K-12 compass is typically a lightweight, clear, and non-toxic liquid, such as a mineral oil or similar substance. This fluid helps to dampen the movement of the compass needle, allowing for smoother and more stable readings. It also protects the internal components from dust and moisture, ensuring the compass remains accurate and reliable over time.
The liquid is there to dampen the movement of the needle. Without the liquid, the needle would spin and jiggle about rapidly. Hence the need to slow the movement down - it makes the compass easier to use.
chemical change,because the liquid form inside the ice candy plastic,changed into a solid particles and getting iced.
It is inside the same part that displays the compass direction.
The first compass was invented around the year 1044. Modern liquid magnetic compasses stem from the mariners compass that was invented in Europe around 1190.
The liquid inside your head is called cerebrospinal fluid (CSF). It surrounds the brain and spinal cord, providing cushioning and protecting them from injury. It also helps to remove waste products and regulate the chemical environment of the brain.
A compass and straight edge.
Swallowing the liquid in a glowstick can cause irritation, discomfort, and an upset stomach. The chemical inside is typically not toxic, but it is recommended to seek medical advice if ingested.
