1 litre tank water sealed does steam pressure rise linear or exponential?

Click For Summary
SUMMARY

The discussion centers on the behavior of steam pressure in a sealed 1-liter container of water when heated from 50°C to 200°C. It is established that the steam pressure does not rise linearly; instead, it increases exponentially, particularly above 100°C. The ideal gas law can be applied to estimate the pressure changes in the steam phase, assuming the water behaves like an ideal gas in the sealed environment. This understanding is crucial for anyone looking to build a system involving steam pressure.

PREREQUISITES
  • Understanding of the ideal gas law
  • Basic thermodynamics principles
  • Knowledge of phase changes in water
  • Familiarity with pressure-temperature relationships in closed systems
NEXT STEPS
  • Research the ideal gas law and its applications in steam pressure calculations
  • Study the phase diagram of water to understand phase transitions
  • Learn about thermodynamic properties of water and steam
  • Investigate safety measures for working with pressurized systems
USEFUL FOR

Engineers, physicists, hobbyists, and anyone involved in designing systems that utilize steam pressure or require an understanding of thermodynamic principles.

hi, if you had a litre container full of water with negligible air and nothing else and heated it at a linear rate from 50 degrees centigrade upto 200 degrees centigrade does the steam pressure rise linearly or exponentially?
the measurements are plucked from the air, its the rate of steam pressure increase above 100 deg c in a sealed tank I am interested in.

i failed science at school and need this confirmed before i build something. thanks

Is the heat input linear, energy added per time, or the temperature rise, degrees centigrade change per time?
 
Worst case estimate, consider the water to be an ideal gas. Adding energy to an ideal gas in a closed, thermally insulated container one can just use the ideal gas law to find the pressure?
