When measuring a small quantity of liquid which instrument would permit the most accurate reading?

If available, a small, glass graduated cylinder would be best. Next best would be a test tube or any clear or semi-transparent cylinder/ small plastic recycled container/bottle. If an eyedropper is not available, recycle a milkshake straw to move/transfer small quantities of a liquid. Place the bottom end of the straw in the liquid almost to the bottom. Then hold your thumb tightly to the top end of the straw and lift out of the liquid. When you remove your thumb the contents will spill out of the bottom of the straw.

What glassware provides the most accurate volume?
The glassware that provides the most accurate measurement of volume is the measuring cup. A glass measuring cup has lines on it to give an accurate reading.
Why do you always have to set the scale back to zero before measuring the mass of another object?
Ensures an accurate reading, this is extremely important when mixing chemical compound's.
How can you tell how accurate a measurement is?
To check the precision of an instrument its apparent measurement must be compared to a known measurement. The difference between the measured quantity divided by the known quantity is expressed as a % precision of the instrument, or calibration. Most instruments when being calibrated are tested against multiple known quantities throughout the range of the instrument. Thus the precision of the instrument is determined throughout it's full range of measurement.
Why is lab thermometer can't be used as clinical and vice - varsa?
A clinical thermometer typically shows a maximum reading while a lab thermometer typically shows the temperature right now. When you take a thermometer out of a patients mouth (or other place that you are measuring the temperature) you most often want the maximum temperature to keep showing until you reset the instrument. When using a lab oratory thermometer you want the instrument to react as quickly as possible so that changes (up and down) can be noticed and recorded.
Science process skill form 1 6.6?
name a type of balance which gives very accurate reading of the mass of an object
When measuring a small quantity of liquid which instrument would permit the actual reading?
Pipette ?
When measuring a small quanity of liquid which instrument would permit the most accurate reading?
Volumetric pipette.
What provides the most accurate volume?
The glassware that provides the most accurate measurement of volume is the measuring cup. A glass measuring cup has lines on it to give an accurate reading.
Why should you leave the thermometer in the liquid while you are measuring its temperature?
The reading is not accurate if it is not in the liquid that you are measuring. Once you take it out, the temperature will be measuring the air.
What instrument gives the same reading each time it makes the same measurement?
A precise instrument. It is not necessarily accurate.
Why you prefer upper arm for measuring bp?
larger veins for a more accurate reading
The reading of instrument is 7.82 what is the correct reading?
No one can answer that as we don't know what instrument is it and what is it measuring in. Also, the reading of an instrument is already the correct reading unless there is a change. Therefore, this question is unanswerable. If this is a homework question, either you have misread the question/left something out or your teacher made a BIG blunder.
What glassware provides the most accurate volume?
The glassware that provides the most accurate measurement of volume is the measuring cup. A glass measuring cup has lines on it to give an accurate reading.
What is the difference between an error as a percentage of full scale or an error as a percentage of reading?
Error as a percentage of full scale is established by multiplying the error percentage by the full scale flow. The less you flow through the device the less accurate the reading will be. For that reason, you don't want to get a larger device than you need. Devices with error expressed as a percentage of full scale are most accurate when flowing at full scale.Error expressed as a percentage of reading expresses error as a percentage of what the device is actually flowing. Simply, if a instrument's accuracy is rated to +/-1% of reading an instrument will be accurate to +/-1% of whatever the instrument is flowing. At 100SLPM the instrument will be accurate to within +/-1SLPM, and at 10SLPM of flow the unit will be accurate to within +/-.1SLPM.
What is the use of barometer in detail?
barometer is an instrument used to measure the pressure in the atmosphere and it also gives as an accurate reading.
How burette is more accurate than measuring cylinder?
burette gives a much finer volume reading than a measuring cylinder and all the chemicals can be placed inside it at the start of the experiment.
Why do you always have to set the scale back to zero before measuring the mass of another object?
Ensures an accurate reading, this is extremely important when mixing chemical compound's.
