What else can I help you with?
The capillary tubing has a uniform bore in a mercury thermometer?
yes ! to insure linearity
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.
Why would the water level increase in the capillary tube during the investigation because of osmosis?
The water level increases in the capillary tube due to osmosis because the concentrated sugar solution in the dialysis tubing creates a lower concentration of water molecules inside the tubing. This lower concentration of water inside the dialysis tubing creates a concentration gradient that drives water to move from the beaker outside the tubing into the tubing through osmosis, causing the water level in the capillary tube to rise.
What is a thermometer bore?
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.
How does the size of capillary bore of a thermometer affect its accuracy?
As the temperature rises, the mercury expands into a narrow bore, because the volume of the mercury increases. If the bore is very narrow then the extra volume has to go a longer way up the bore to accomodate that volume, so it is more sensitive to small changes of temperature. And it is easier to spot small changes of temperature, and read them from the scale more accurately. But if the scale isn't marked accurately in the first place you are no better off.
Which is the best description of a conical bore instrument?
The size of the tubing gradually increases throughout the length of the instrument.
How do you measure ACR tubing?
As ACR tubing appears to be copper pipes, a tape measurer can be used to measure the length of tubing. A ruler can be used to measure the width and the bore of the pipes. If still not sure, take a small length of pipe to the supplier.
What is the bore of a cappillary tube?
The bore of a capillary tube is the inner diameter of the tube, which is very small typically ranging from below 1 millimeter down to a few micrometers. It is designed to facilitate the movement of liquids through the tube using capillary action.
The rise of water in a narrow test tube is called?
The rise around the edges is called the meniscus, like capillary action this is caused by the adhesion of the liquid molecules to the walls of the container. In a large bore tube like a test tube or graduated cylinder this pulls up the edge and creates a concave meniscus, in a smaller bore tube this actually pulls the liquid toward the top of the tube.
How should you do to increase the accuracy of the thermometer?
using a thin capillary bore using a thick glass stem
What has greatest capillary action?
Water has the greatest capillary action due to its strong hydrogen bonding and cohesive properties, allowing it to easily move through narrow spaces and against gravity. Other liquids with high capillary action include mercury and ethanol.
Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
The narrow capillary bore allows for more precise measurement of temperature changes because the mercury expands and contracts more readily in the smaller tube. This enables the thermometer to detect even small variations in temperature accurately.
