In a barometer, if we replaced the mercury with alcohol and water?

SUMMARY

This discussion centers on the behavior of fluids in a barometer when replacing mercury with alcohol and water. It establishes that alcohol, with a density of 800 kg/m³, can be displaced further than water, which has a density of 1000 kg/m³, under the same pressure conditions. The key factor is the relationship between fluid density and pressure, as described by the hydrostatic pressure equation, P = ρgh, where P is pressure, ρ is density, g is gravitational acceleration, and h is the height of the fluid column. The discussion emphasizes the importance of understanding fluid dynamics and density in predicting fluid behavior under pressure.

PREREQUISITES
  • Understanding of hydrostatic pressure principles
  • Familiarity with fluid density concepts
  • Knowledge of Bernoulli's principle
  • Basic chemistry of alcohol and water
NEXT STEPS
  • Research the hydrostatic pressure equation and its applications
  • Explore the properties of different fluids, focusing on density and viscosity
  • Study Bernoulli's principle in-depth and its implications in fluid dynamics
  • Investigate the chemical properties of alcohol compared to water
USEFUL FOR

This discussion is beneficial for physics students, chemists, and engineers interested in fluid dynamics and barometric principles, as well as anyone studying the effects of fluid density on pressure measurements.

In a barometer, assuming bernoulie properties(incompressible fluid) if we replaced the mercury with alcohol and water why would the alcohol be able to be displaced further with pressure. It has a lower density that water 800kg/m^3 than water which has 1000kg/m3.

What chemical properties or properties due to density would give us the result where alcohol can be moved up further when we apply the same pressure.
