Make sure you label it as liters, etc not grams or meters

Give an instance or a situation that describe a parallax error?
in optical instruments,while measuring the lenght,the object and the image must overlap,if not it would show parallax error.
IF The weight of a rock is measured at 2.5 pounds what is the percent error in this measurement?
It depends on the calibration of the instrument you are measuring with.
What is the purpose of determining the average density for each liquid in this experiment with different glassware?
to find the percentage of the relative error
Will density of a liquid increase if parts of the solid sticks out of the water?
No. Density is an intrinsic property and does not depend on the amount or size of the sample. If you are referring to finding the volume of an irregular solid by water displacement, then you will get a very large experimental error if the solid sticks out of the water. The amount of water added to the graduated cylinder initially, must be enough to completely cover the solid, before you place the solid in the cylinder.
How do you measure the dry and liquid ingredients?
Video: How do you measure dry ingredients?Measuring Dry IngredientsThe basics of measuring dry ingredients is the same for all, whether it's flour, sugar, salt, or another dry ingredient. To measure dry ingredients, select the appropriate measuring cup or spoon. Place the dry ingredient in the measuring device so that it fills and overflows the device. Use a utensil with a straight edge (an icing spreader works well) to scrape off the excess.Special circumstances:Flour - When measuring flour, spoon it into the measuring device and do not tap it down.Brown sugar - Pack it firmly into the measuring device.
Which instrument is suitable for measuring 230cm3 of liquid?
100cm 3 measuring cylinder. Unless you want to use a 50.00 cm3 burette but the percentage error would be high for that
Why is use of zero error necessary in a measuring instrument?
Zero error is necessary for measuring instruments for measuring accurate results because it helps to check that the instrument which we are using is whether correct or wrong
What causes systematic error?
Improper calibration of the measuring instrument. If the measuring instrument is not at zero prior to measuring the object you will get a systematic error which, is a value either always higher or always lower then the actual value of the object.
What meant by the tolerance of a measuring instrumental?
Intrinsic error.
What are some possible sources of errors in the lab?
Some possible sources of lab error. 1. Not preciously measuring. 2 Air pressure (not being at STP). 3 Not all liquid evaporating when measuring a solid. 4 How many significant digits are used and when rounded
What is the name of the error when amount in figure differs from amount in words?
conversion error
What is the most useful descriptive statistic of measuring dispersion?
The standard error.
What are the sources of error in measuring heart rate by palpation?
stop watch
How do you avoid systematic error?
A systematic error is a reproducible inaccuracy with a nonzero mean. It can be avoided by ensuring that the measuring equipment is not flawed.
What type and source of error when or while using vernier caliper?
The Vernier caliper is an extremely precise measuring instrument Error is almost impossible The error that we must always look out for is the zero error and parralex error.
What is zero error in vernier caliper?
The zero error of a measuring instrument is the measure that it shows when it should actually be showing zero.
What is the greatest possible error when measuring to the nearest quarter of an inch in fraction?
An eighth of an inch.
