================================================================== How to measure volume ? Cubic kilometre - 1km = (1 000 x 1 000 x 1 000) m3 = 1 000 000 000 m3 Cubic metre (S1 Unit) - 1 cubic metre = (100 x 100 x 100) centimetre cube = 1 000 000 centermetre cube = 1000 litres Cubic centimetre - 1 centimetre cube = (10 x 10 x 10) milimetre cube   Measuring Cylinder It is a glass or transparent plastic cylinder used for measuring liquid volumes, especially in chemical analysis.A measuring cylinder is also known as a graduated cylinder.  Beaker It is a cup usually having a wide mouth a plastic beaker and a puring lip. The use of the beaker is to hold and pour liquids . They can also be used to heat liquids. It is really just a round glass container with a flat bottom. They come in many sizes, from tiny ones that only hold 10 mL to giant ones that hold many liters.  Pipette The pipette is also called the pipet ,pipettor or chemical dropper.They are used in a laboratory to transport and/or measure a specific volume of liquid.  Burette Burettes measure from the top since they are used to measure liquids dispensed out the bottom. The difference between starting and final volume is the amount dispensed. parallax error is the error in measurement due to eye not positioned perpendicularly at the the mark on the scale.  READING THE MENISCUS is a curve in the surface of a molecular substance and is produced in response to the surface of the container or another object.  A:the bottom of a concave meniscus. B:the top of a convex meniscus. Irregular Solids: use a displacement can or a measuring cylinder. For example: I have a golf ball and i want to know whats the volume of it. i can use either a displacement can or a measuring cylinder. Using a measuring cylinder: i put 20mL of water in it. i put the golf ball in the measuring cylinder. make sure no water splats out.Then read the reading,for example 100mL. Therefore the volume of the golf ball is 100mL-50mL=50mL |
