Why does a mercury-in-glass laboratory thermometer have a narrow capillary bore?
To increase the sensitivity of the thermometer, that is, for the thermometer to respond quickly to small changes in temperature.
What does the sensitivity of thermometer depends on?
The difference between the coefficients of thermal expansion of the liquid in the thermometer bulb and the material of the bulb.
What is the sensitivity of an instrument?
The sensitivity of an instrument is the smallest amount it can measure, of whatever it's built to measure.Anything smaller than the sensitivity of the instrument, and the instrument doesn't even notice it.For example, a laboratory scale can measure the weight of a hair, but a truck scale can't. We say that thelaboratory scale's sensitivity is much smaller (or lower) than the truck scale's sensitivity.
How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
Why thermositor is more appropriate for measuring than thermometer?
It can give an electrical output (change in resistance) which is often helpful and can have a higher sensitivity. Also easier to fit in tight places.
A thermometer has a high sensitivity'?
yes

What is hyperesthesia in lumbosacral region?
increased sensitivity to touch in the lower back
How do you increase sensitivity of mercury in glass thermometer?
Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. More sensitive means more noticeable expansion. So if you want to increase the sensitivity, you could have a thinner capillary tube, a larger thermometer bulb etc. :)sailesh
Does the aereola itch during pregnancy?
yes, increased sensitivity to the area is normal during pregnancy.
What are hypotyroidism symptoms. what does it do?
Reduction in body weight, sleeplessness, buldging eyes, increased body temperatures, heat sensitivity, increased metabolism, excess hunger.
How do you 360 shot in COD4?
set your sensitivity up to very high, jump and with increased sensitivity you should be able to pull a 360 turn of a large jump and then its timing really
Can a nightguard cause teeth sensitivity?
Yes, a nightguard can cause teeth sensitivity if it is new or if it is not fitted properly. Some sensitivity with a new guard you are not used to can cause increased sensitivity, but if it causes too much of an issue later on, you should speak with a dentist about getting a new molded guard made.
What causes light and sound sensitivity during migraines?
Light and sound sensitivity during Migraine is caused by the neurological processes of the attack. Increased pressure is not related to Migraine and in fact is another headache disorder called Intracranial Hypertension._____________________________________________Increased pressureBlood vessels are expandig and increasing intracranial pressure which affects certain cranial nerves which leads to pain and increased light/sound sensitivity.
Malnutrition causes what eye problems?
Visual disturbances include night blindness and increased sensitivity to light and glare.
