Question

A student set up an apparatus for finding boiling point of water at Shimla. The thermometer
is accurate, but it shows the boiling point to be 97 0C. The reason is
a. High pressure of air at high altitude.
b. Low pressure of air at high altitude.
c. Water may be containing large amount of dissolved air.
d. It is not distilled water

Answer 1

Answer:

c

Explanation:

Two reasons, impurities and pressure, impurities (minerals of any kind that are naturally present or added for various reasons) raise the boiling point of a liquid, also atmospheric pressure changes, usually due to altitude, if you’re at high elevations water will boil at a lower temperature and you’ll notice things that you cook in water such as pasta or hard boiled eggs take longer to cook because water will not reach 212 f or 100 c
