- The general rule of thumb is: you can estimate one more digit past the smallest division on the measuring device. If you look at a 10mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1mL). That means when you read the volume, you can estimate to the hundredths place (0.01mL). Portion of a 10mL graduated cylinder Use the bottom of the meniscus to determine the volume in the 10mL graduated cylinder. Since the smallest division (graduation) is a tenth of a milliliter, we can estimate to a hundredth of a milliliter (0.01). 3.87mL

High School Chemistry/Making Measurements Look at the two figures above; if you were required to measure out 65 mL, what instrument would you most likely want to use? The graduated cylinder has graduations every 10 mL and then further graduations every 5 mL. The beakers could have graduations every 10 mL, 50 mL, or 100 mL depending on which type you use.

- Exercise 5: What is the efficiency of a machine that has work inputof 40 joules and work output of 35 joules? Exercise 6: Work output of a large machine in a factory is 89,000 joules, and its input is 102,000 joules. Pearson Education, Inc., publishing as Pearson Prentice Hall. All rights reserved. Section 14.3 Mechanical Advantage and Efficiency Efficiency Because some of the work input to a machine is used to overcomefriction, work output is always less than work input.

The Effect of Molecular Weight on the Diffusion Rate of Substances1 In the agar-water gel test, drops of potassium permanganate, potassium dichromate and methylene blue were simultaneously placed in separate wells in an agar plate. Methylene blue, with the largest molecular weight, had the smallest diameter (8.5 mm) and had the slowest diffusion rate (0.05 mm/min).

- The Middle Ages, by a tortuous route from Babylon, inherit a scale of scientific measurement based on 60. In medieval Latin the unit of one sixtieth is pars minuta prima ('first very small part'), and a sixtieth of that is pars minute secunda ('second very small part').

What is Least count? All measuring instruments used in physics have a least count. A meter ruler's least count is 0.1 centimeter; an electronic scale has a least count of 0.001g, although this may vary; a vernier caliper has a least count of 0.02 millimeters, although this too may vary; and micrometer screwgauge's least count is 0.01 millimeter. Most instrument have this item marked on it.

- If you are using a graduated cylinder or measuring cup with volume measurements on the side, you do not need to make a mark. Just look for the volume measurement at the water's surface, and write this number down.

- The basic unit of volume in the metric system is the liter (symbol is L or l). unit used for small amounts of liquids is the milliliter (mL) (10-3 or 1/1000 of a liter). bottle of spring water might hold 500 mL (half a liter) of liquid. The volume of a milliliter is equal to the volume of a cube 1 centimeter per side. expressed as cc (cubic centimeters) such as on the side of a medical syringe.

Working with Exponents and Logarithms the log of division is the difference of the logs : log a (1/n) = −log a n: this just follows on from the previous division rule, because log a (1) = 0 : log a (m r) = r ( log a m) the log of m with an exponent r is r times the log of m

- If you wanted to, you could weigh out the water on a balance, but graduated cylinders can more easily measure liquid volumes greater than 10 mL. Choose a graduated cylinder with a maximum volume as close as possible to that you want to measure to ensure accuracy. Fill it to nearly the volume you want

Division by zero In ordinary arithmetic, the expression has no meaning, as there is no number which, multiplied by 0, gives a (assuming a≠0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 0/0 also has no defined value; when it is the form of a limit, it is an indeterminate form.

- The measuring cylinder (Figure 6.4) is transparent, and is graduated in units of precipitation. Rainwater entering through the receptacle accumulates in the storage bottle, and the precipitation amount is measured with the measuring glass. Rainwater that overflows from the storage bottle enters the storage vessel.
