How can you make your vernier callipers more sensitive or more accurate?
the instrument can be made more sensitive by making vernier constant less ie by incresing the no of division on vernier scale or by decreasing the value of main scale.
What does a thermistor do that makes it different from a thermocouple?
a thermistor is a temperature sensitive resistor - to measure temperature you must measure its resistance and convert that resistance to equivalent temperaturea thermocouple is a temperature sensitive voltage source(i.e. battery) - to measure temperature you must measure the voltage across it and a reference thermocouple at a known constant temperature connected in series with it and convert that voltage to equivalent temperatureNote: Thermistors do not require reference thermistors, thermocouples do require reference thermocouples at a known constant temperature. Thermocouples are more linear than thermistors, making them easier to read accurately. Thermocouples are available that are far more sensitive to small changes in temperature than thermistors.
What is advantages of thermistor?
A thermistor an electrical resistor that resistance changes with temperature. There are two advantages of a thermistors one is it been more sensitive that the RTDÕs and thermocouples and two is has a quick response time.
Why as load increase the condenser temperature will also increase?
Because the more the load the more the temperature.
Are the similarities between the UJT and BJT?
PNPOperates on minority charge carriers (holes).Slower than NPN because holes are less mobile than electrons.Slightly easier to manufacture than NPN.More sensitive to high temperature due to thermal hole generation.etc.NPNOperates on minority charge carriers (electrons).Faster than PNP because electrons are more mobile than holes.Slightly harder to manufacture than PNP.Less sensitive to high temperature.etc.
Why do you use kelvin scale?
Kelvin Scale is an absolute temperature scale. This means that it starts at a different point than Celsius, its counterpart. This is why you must add 273.15 to a Celsius temperature in order to get a Kelvin temperature. The Kelvin scale starts at absolute zero whereas Celsius starts at the freezing point of water. Kelvin is used more often in science such as in the ideal gas equation. It is more convenient to use it than Celsius when dealing with very cold temperatures and with things like the Perfect Gas Laws which reference absolute zero.
Which is warmer -15 deg Celsius or -3 deg Celsius?
-12
What is Celsius used for?
The Celsius (or Centigrade) scale is the predominant scale used to measure temperature worldwide. The United States is one of only a few countries where the Fahrenheit scale remains more common. A third scale, Kelvin, is used in some specialist applications, such as by physicists.
Which gas is colder -145 Celsius or -245 Celsius and why?
-245 because on the Celsius temperature scale the negative end is cold and the positive end is hot. So as you go more negative you get colder.
How many celsius in one gram?
'Celsius' is the name of a scale of temperature measurement. It has no connection at all with 'gram', any more than you could tell me your age in Fahrenheit.
Is kelvin more or less than Celsius?
One degree in the Kelvin scale is equal to one degree in the Celsius scale. They do however have different 'starting' points. Celsius starts (zero degrees 00 C) at the freezing temperature of water. Kelvin starts (zero degrees 00 K) is at absolute zero. Which is the coldest temperature obtainable. This temperature is equal to -273.150 C
Why is there a celsius temperature scale?
Because it's a lot more sensible than theantiquated Fahrenheit scale which lingers only in you guessed it, the unmetricated USA. The Celsius scale logically has zero degrees as the freezing point of pure water and 100 degrees as the boiling point.
What are the referent points for the celsius scale?
0 degrees celsius indicates the freezing point of water at sealevel with normal air pressure (one standard atmosphere). At 100 degrees celsius the temperature is equal to the boiling point of water. However, a more modern calibration is made in order to make the celsius scale more accurate and to be able to compare the celsius scale with the Kelvin scale even better. The new referent points are: " absolute zero, and the triple point of VSMOW (specially purified water)." But those changes are insignificant for normal, daily use of the scale.
What do you mean by 1 degree celsius of rise in temperature equal to 1 kelvin of rise in temperature of a substance?
1 kelvin and 1 celsius degree are both exactly the same thing ... a unit of temperature, equal to 1/100 of the difference between the freezing and boiling points of water. The only difference between the Kelvin scale and the Celsius scale is that they start from different temperatures ... the Celsius number starts from the freezing point of water, whereas the Kelvin scale starts from 'absolute zero'. So the Kelvin temperature will always be 273.15 more than the Celsius temperature ... because it starts at 273.15 lower. But when the temperature changes by some number of Celsius degrees, it changes by exactly the same number of Kelvins, because 1 Kelvin is exactly the same size as 1 Celsius degree.
Do scientists typically measure temperature using the Fahrenheit scale?
More usually in the United States, but outside they mainly use Kelvin and Celsius.
Why was the Celsius scale called the centigrade scale?
Temperature is not called Fahrenheit or Celsius; temperature is measured in degrees Fahrenheit or degrees Celsius.The names Fahrenheit and Celsius are derived from the creators of the temperature scales: Daniel Gabriel Fahrenheit and Anders Celsius.
What temp scale is used mostly by scientists?
The temperature scale commonly used in science is the Celsius or centigrade scale. The Kelvin scale is most often used in the thermodynamic and astronomical fields (and especially when dealing with temperatures close to absolute zero).There are two temperature scales used by scientists. The first scale, Kelvin, is the SI (Standard Unit) or official unit used in certain cases. Informally, and more commonly is the Celsius scale.The older Fahrenheit scale (and its absolute version, the Rankine) are still used in the US and some other countries, but not generally for scientific purposes to avoid misunderstandings in data comparison.
