Answer:
See in the explanation. Please mark as brilliant.
Explanation:
1.) No, the reading taken at first is wrong.
2.) Beaker is made up of glass, so while heating the water there may be a chance that the beaker may break down or blast. It is very dangerous. A gauze helps us prevent this. Therefore it is safe.
