Factors to keep constant for a fair test:
1. Size of the beaker: The size of the beaker can affect the heat distribution and therefore the time taken for the solution to reach boiling point. By keeping the size of the beaker constant, Abhilasha ensures that the heat distribution is consistent across all the solutions.

2. Amount of solution: The amount of solution in each beaker can affect the rate at which it heats up. By keeping the amount of solution constant, Abhilasha ensures that the heat is applied evenly to each solution, allowing for a fair comparison of the time taken to reach boiling point.

3. Starting temperature of the solution: The starting temperature of the solution can affect the time taken to reach boiling point. By keeping the starting temperature constant, Abhilasha eliminates the variable of initial temperature and focuses solely on the time taken for the solutions to boil.

4. Final temperature of the solution: The final temperature of the solution is not necessary to keep constant in order to carry out a fair test. The objective is to compare the time taken for the solutions to reach boiling point, and the final temperature may vary depending on the specific solution.

Therefore, to carry out a fair test in comparing the time taken for different solutions to reach boiling point, Abhilasha must keep the following factors constant: 1. Size of the beaker, 2. Amount of solution, and 3. Starting temperature of the solution. The final temperature of the solution does not need to be kept constant.
