Why a gas thermometer is more sensitive then a liquid thermometer?
A gas thermometer is more sensitive because...To answer that we first have to do 3 steps.1)What is sensitivity?Sensitivity is the ability to record small changes.2)What does a gas have that other states don't?Easily compressed; has a good range etc.3)Answer?A bit like a ven diagram. taking factors which apply to both steps. Because a gas is easily compressed it won't make any big jumps whilst changing state, making it ABLE TO RECORD SMALL CHANGES, etc.I hope i answered your questions, and helped you (and others) in the future ;)
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.
What makes a liquid in glass thermometer sensitive to a small changes in temperature?
A liquid in glass thermometer is sensitive to small changes in temperature due to the thermal expansion of the liquid contained inside the glass tube. As the temperature increases, the liquid expands, causing it to rise up the calibrated scale of the thermometer. Conversely, as the temperature decreases, the liquid contracts, causing it to subside on the scale. This expansion and contraction of the liquid is highly responsive to even slight temperature variations, making it sensitive to small changes in temperature.
How do you increase the range of a thermometer?
If you're the one designing the thermometer, you could make it longer or make the bore wider. If you've got an existing thermometer, there's not much you can do.
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.
How do you make thermometers sensitive?
You may increase the heat transfer rate to make it more sensitive to environment such as introducing air flow through thermometer in case of measuring air temperature. It can also design thermometer to be more sensitve with better heat sensitive material and thinner insulation wall. Introducing medium into contact surface (such as oil or water in thermowell) would speed up heat trasfer and make it more sensitive to temperature change.
Which thermometr will you take when you go to south expedition mercury or alchol?
An Alcohol thermometer would be the best as it is more sensitive than the mercury thermometer.
Which one is more sensitive in between two thermometer one having spherical bulb and another having cylindrical bulb?
cylindrical bulb is more sensitive than the spherical bulb.
Why are bi-metallic thermometer helical shape?
So that they can move a needle in a round dial, the more helical windings the more sensitive the reading.
What is a Beckmann differential thermometer?
A sensitive thermometer with an adjustable range so that small differences in temperature can be measured.
Which thermometer (water or air-filled) is more sensitive?
water filled because it is more accurate in terms of temperature calibrating so it makes those exact marks to well.. be exact

What is a clinical thermometer?
A clinical thermometer, this type of thermometer is sensitive to very small changes in temperature but is able to measure temperatures only within a few degrees of normal body temperature (thirty seven degrees celsius).
Which apparatus is more accurate clinical thermometer or laboratory thermometer?
Lab thermometer.
