dprpikin:
i) 25°C
ii) 88°C
a) 250°C

b) This is because the material of the thermocouple has very low heat capacity, hence on removal from the source of heat the temperature falls very quickly, causing the sharp fall in the reading of the millivoltmeter.

Please can you work it on a paper and snap then I can concur and u get ur reward.... Thank you
Then pm me for ur card....

Before I solve it in the paper, confirm whether the pressure is 700mmHg or 760mmHg?

The pressure is irrelevant. It's just a distraction.

You can re-snap the workings tomorrow for better view..... Plz pm for your card.

Here is it

There is nothing in that question asking you to state the temperature at normal pressure.

dprpikin:

This question is one that involves a bad thermometer. What we are doing basically, is to compare the reading of the bad thermometer with what a good thermometer would have read. And in doing so we need to know the accurate boiling point at 700mmHg.

Since steam obeys the ideal gas laws, we can now use the ideal gas equations. To apply this equation we need another set of boiling point and pressure. That is what led to quoting the boiling point of water (100°C), at standard atmospheric pressure (760mmHg).

We are not concerned with the melting point, as pressure does not affect the melting point of ice. And of course, ice does not obey the ideal gas laws.

Regelation?
