The city of Manila held a trial run its newest program which is the Acid and Base Tournament. All of the participants enjoyed the program. But the city mayor noticed that there were traces of spilled liquid on the metal trays where the towels were place. The mayor was anxious because the towels were burnt and the metal trays were damage. The mayor ask for help from the committee and one of the officials suggested to consult you as the chemist. You are going discuss what happened with the damaged metal trays and burnt towels when the liquid was spilled on them. Suggest an alternative material or way to prevent the same incident to happen again.
OUTPUT: You are going to present a cause and effect discussion o the mayor of the city. You will be reporting next week. First, analyze what happened by examining the characteristic of the materials involved. Then, research on the possible solutions that you are proven to be effective. Make a slide presentation of your output.

Not sure, do I need to prepare a presentation?

Explanation:

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.
