Is mercury in any devices always in a capillary tube?
A thermometer has a capillary tube but a mercury switch in a heater thermostat has mercury that just rolls back and forth.
When bright red mercury (II) oxide is heated in a test tube oxygen gas is evolved and droplets of liquid mercury condense at the cooler top of the test tube.?
Yes, it is correct.
What is the danger in heating a test tube?
The materials in the tube could chemically combine, releasing energy, or they could boil, burn, or explode. Any of these is a hazard if the material escapes from the tube or breaks it open. The glass in the tube could also fracture or break with improper heating.

Design an experiment to test the air pressure at different altitudes?
The historical experiment is to create a long, thin glass tube, sealed at one end. Immerse the tube in liquid Mercury then stand it upright so that there is an evacuated segment at the top (sealed) end of the glass tube. Then walk up a mountain and not how the height of the mercury in the tube changes. Warning: Mercury is poisonous, deadly so after long exposure.

What pushes Mercury up in a tube of a Mercury barometer?
That depends on the 'tube' involved. In a thermometer the mercury expands and contracts within a sealed tube as the temperature is raised or lowered. In a barometer there is a reservoir of mercury which the atmosphere presses on. This maintains the mercury in a column which is sealed at the top. Increases in atmospheric pressure push the mercury further up the tube, decreases let it drop down the tube.
Why mercury falls in capillary tube?
because,the adhesive force of mercury in more compared to the cohesive force which acts on a capillary tube. that's why mercury falls in capillary tube
What is a control test tube?
There are many uses of the electromagnet, it is used to invent generators and electric motors, used it to control the switch relay, use in practical industries, and even in an electric bell etc. Because the electromagnet is a type of magnet in which the magnetic field is produced by the electric current.
