In an electric fan, electrical energy changes into mechanical energy. True/False.

Answer

To determine whether the statement "In an electric fan, electrical energy changes into mechanical energy" is true or false, we can follow these steps:

### Step 1: Understand the Function of an Electric Fan
An electric fan operates by using electricity to power its motor, which causes the blades of the fan to rotate.

**Hint:** Think about what happens when you turn on a fan. What energy is being used?

### Step 2: Identify the Types of Energy Involved
In this case, the energy supplied to the fan is electrical energy (from the power source). The energy that is produced by the fan's operation is mechanical energy, specifically in the form of rotational energy as the blades spin.

**Hint:** Consider the energy input (what you provide) and the energy output (what the fan does).

### Step 3: Analyze the Energy Transformation
When the fan is turned on, the electrical energy is converted into mechanical energy. This transformation is essential for the fan to perform its function of moving air.

**Hint:** Remember that energy can change forms. What is the fan doing with the electrical energy?

### Step 4: Conclusion
Since the electric fan takes electrical energy and converts it into mechanical energy, the statement is true.

**Final Answer:** True.
