Data obtained from the question include:
V1 (initial volume) = 1L
T1 (initial temperature) = 315K
P1 (initial pressure) = 1.10 atm
T2 (final temperature) = stp = 273K
P2 (final pressure) = stp = 1atm
V2 (final volume) =?
Using the general gas equation P1V1/T1 = P2V2/T2, the final volume of the system can be obtained as follow:
P1V1/T1 = P2V2/T2
1.1 x 1/315 = 1 x V2/273
Cross multiply to express in linear form.
315 x V2 = 1.1 x 273
Divide both side by 315
V2 = (1.1 x 273) /315
V2 = 0.95L
Therefore, the final volume of the system if STP conditions are established is 0.95L
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.
