- Q1. 1) Introduce yourself and elaborate about your academic projects
- Q2. 2) What will happen to the boiling point of the water if salts are added to the boiling water?
- Ans.
Adding salts to boiling water increases the boiling point of water.
Adding salts to boiling water increases the boiling point due to the phenomenon of boiling point elevation.
This is because the presence of solute particles in the water disrupts the formation of vapor bubbles, requiring a higher temperature to boil.

You will undergo a written test comprising three coding sections (either in Python or C) containing five or six questions each, along with ten multiple-choice questions on software testing, which are relatively easy.
