capillary tube is not really sealed securely. there are tiny gaps between the cells that forms the wall of cappilary tubes which allows certain materials to pass through (eg. nutrients, oxygen, carbon dioxide). It is just not permeable to your blood cells cause if it does, your body will be insufficient of blood cells

What steps can you take to determine the melting point of a substance that sublimes before it melts?
In such cases the melting point determination must be performed in a sealed capillary tube to avoid loss of sample. This can be achieved by heating the open end of the capillary tube, and with tweezers forcing it shut.
The height of a liquid in a capillary tube is not dependent on?
the height of a capillary tube is not dependent on
Describe the structure of a thermometer?
The thermometer consists of a very fine glass tube having a very small bore and is called capillary tube. At one end of capillary tube a very thin glass bulb is provided. The bulb is filled with mercury( most of the times) or alcohol The other end of capillary tube is sealed. The capillary tube is protected by a thick glass tube called stem. On the stem are made markings. These markings are called graduations or degrees.
Why is a capillary tube thought of as a dry-type?
The Capillary tube metering device is used primarily on small fractional-horsepower refrigeration systems that have relatively constant evaporator heat loads. These systems are hermetically sealed, leak free systems with dry-type evaporators that use a minimum of refrigerant. The capillary tube metering device is a fixed bore device, itcontrols refrigerant flow by pressure drop.
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
Why is capillary tube fixed in Ostwalds viscometer?
The capillary tube is fixed in the Ostwalds viscometer is for passing the liquid.
What is the function of capillary tube?
The capillary tube is used on the inside of the refrigerators. It is a long copper tubing that is used as a thruster.
Excess superheat in a capillary tube system means that there is?
