Directions: Create a data table on the student handout based on the information given below. Use the graphing notes as a resource.
All of the science teachers have a guinea pig. Which of the guinea pigs
ate the most food based on two days on food consumption. On day 1,
Mrs. Garcia's ate 65 gm, Mrs. Brody's ate 105 gm, Mr. Smith's ate 85 gm,
Mrs. Nguyen's ate 93 gm, Mr. Black's ate 150gm, and Mrs. Miller's ate 97
gm. On day 2, Mrs. Garcia's ate 85 gm, Mrs. Brody's ate 90 gm, Mr.
Smith's ate 100 gm, Mrs. Nguyen's ate 150 gm, Mr. Black's ate 85 gm,
and Mrs. Miller's ate 125 gm.
Consider the data and how many columns and rows you will need to
display it.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
