Discussion Overview

The discussion revolves around the boiling point of water when the pressure inside a cylinder is raised to 500 kPa. Participants explore the relationship between pressure and boiling point, considering both theoretical and practical aspects.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant initially suggests that water would start boiling at 150 °C under 500 kPa pressure.
  • Another participant questions the validity of the 150 °C figure, expressing skepticism about its accuracy.
  • A later reply corrects the initial claim, stating that water boils at 100 °C at atmospheric pressure, but acknowledges that the boiling point increases with pressure.
  • Another participant asserts that water boils at a temperature higher than 100 °C at 500 kPa and suggests consulting boiling point tables for precise values.

Areas of Agreement / Disagreement

Participants do not reach consensus on the exact boiling point at 500 kPa, with differing views on the initial temperature suggested and the acknowledgment that it is higher than 100 °C.

Contextual Notes

The discussion lacks specific boiling point data for water at 500 kPa and does not resolve the assumptions regarding the relationship between pressure and boiling point.

1 - If the pressure inside cylinder raised to 500 Kpa when the water would start boiling ? and if some of the water heated from 0 degree to the atmospheric pressure when the water start boiling ?

my answer
A )
when it reach temperature of 150 degree

b )
when it reach temperature of 100 degree

Where did you got this number from? Looks a little bit too high for me.
 
because as I know when 100 C the water will start boiling

sorry not 150 just 100 C
 
No, water definitely boils at more than 100 °C at 500 kPa. Question is - how much. The easiest approach is to look for boiling point tables.
