Answer

Answer:

It is used for making different reactions visible in a wider space.

Explanation:

Step1: Understand Petri - dish function

A Petri - dish is a flat, shallow dish with a lid used in labs.

Step2: Analyze options

  • Option 1: A Petri - dish is not used to seal a beaker during mixing.
  • Option 2: It is not mainly for catching and directing liquid flow.
  • Option 3: Its flat and open nature allows reactions to be easily observed in a wide area, which is correct.
  • Option 4: It is not used for creating a specific concentration and volume of a solution.
