Answer:
two variables.
Explanation:
a controlled experiment requires at least two. variables.
Movement of molecules depend on the viscosity of the medium and kinetic energy.
<h2>Role of medium for movement of molecules</h2>
Water in a freezer are in hard form so the molecules are in rest form due to hard medium and no kinetic energy. Due to this hard medium, freedom of movement of water molecules are not possible so they remain in static position.
<h3>Effects of Kinetic energy </h3>
While on the other hand, water on a stove are in liquid form in which molecules are moving continuously because temperature of water increases which increases the kinetic energy of the water molecules. This high kinetic energy allows the molecules of freedom of movement in the medium.

In the context of the planning process, implementation of selected plans will be most successful when: <span>they are linked to other organizational systems like budgets and rewards
Selected plans refer to a proper choice of plans that suitable for each problem/situation.
To execute these type of plans, we need the flexibility and a fully cooperative effort from all employees and in order to get that cooperative effort. In order to get both flexibility and the cooperative effort, budget and reward system could be a strong incentive for the employeess</span>
