Volume Of Liquid
What is volume?
Volume is defined as the amount of space taken up by a three-dimensional object.
Volume often refers to liquid volume, which is defined as the amount of space taken up by a liquid, which spreads completely to fill its container.
What is liquid?
Things that is melt
Things that can flows
Liquid takes the shapes of the container.
Example:
Look at the picture.
There are various of container with liquids.
Which container has more liquids?
How to measure?
We use a measure beaker or measure cylinder to measure the volumes of liquids.
Measuring Volume Of Liquid
Measure the volume of water in the beaker.
EXAMPLE:
1. Pour the water from the beaker into the measuring cylinder.
2. Read the scales.
How to read ?
Put your eyes at the same level with the water level.
3. When the water level reach 80 ml, the volume is 80ml.
4. When the water level reach 90ml, the volume is 90ml.
5. When the water level reach 100ml, the volume is 100ml.
Comparing Volume Of Liquid
Look at the picture.
Which cylinder has more liquid??
How to compare?
1. First pour the liquid into a measuring cylinder.
2. Then read the water level at cylinder A.
20ml
2. Then read the water level at cylinder B.
60ml.
3. The result: Cylinder A has less 20ml liquid than cylinder B.
Cylinder B has more 20ml liquid than
