Question

1. How can you determine the boiling point of water​

Answer 1

Answer:

Take about 25ml of distilled water in a boiling tube and add 2-3 small pieces of pumice stone. 1.Close the mouth of the boiling tube with a rubber cork that has two bores and clamp it with the stand. 2.Introduce a thermometer (temperature range -10 to 110°C) in one bore of the cork of the boiling tube.

hope that helps

Answer 2

Answer:

Calculating boiling point based on pressure can be done using several different formulas. These formulas vary in complexity and accuracy. In general, units in these calculations will be in the metric or System International (SI) system, resulting in temperatures in degrees Celsius (oC). To convert to Fahrenheit (oF), use the conversion T(°F) = T(°C) × 9÷5 + 32, where T means temperature. As for atmospheric pressure, the pressure units cancel out, so which units are used, whether mmHg, bars, psi or another unit, is less important than being sure that all the pressure measurements are the same units.
