MEASURE AND COMPARE VOLUME OF LIQUID

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 Cylinder A.

Beauty of Mathematics !!!!!!!

1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321

1 x 9 + 2 = 11
12 x 9 + 3 = 111
123 x 9 + 4 = 1111
1234 x 9 + 5 = 11111
12345 x 9 + 6 = 111111
123456 x 9 + 7 = 1111111
1234567 x 9 + 8 = 11111111
12345678 x 9 + 9 = 111111111
123456789 x 9 +10= 1111111111

9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888

Brilliant, isn't it?

And look at this symmetry:

1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111 = 12345678987654321



Now, take a look at this...


101%



From a strictly mathematical viewpoint:



What Equals 100%?
What does it mean to give MORE than 100%?

Ever wonder about those people who say they are giving more than 100%?

We have all been in situations where someone wants you to
GIVE OVER 100%.

How about ACHIEVING 101%?


What equals 100% in life?


Here's a little mathematical formula that might help
answer these questions:


If:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Is represented as:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26.


If:


H-A-R-D-W-O- R- K


8+1+18+4+23+ 15+18+11 = 98%


And:

K-N-O-W-L-E- D-G-E


11+14+15+23+ 12+5+4+7+ 5 = 96%


But:

A-T-T-I-T-U- D-E


1+20+20+9+20+ 21+4+5 = 100%



THEN, look how far the love of God will take you:



L-O-V-E-O-F- G-O-D


12+15+22+5+15+ 6+7+15+4 = 101%


Therefore, one can conclude with mathematical certainty that:

While Hard Work and Knowledge will get you close, and Attitude will
get you there, It's the Love of God that will put you over the top!

It's up to you if you share this with your friends & loved ones just
the way I did..
