The _______ precipitator is a device that removes minute particles present in smoke by applying electricity through it and attracting the particles towards itself.

Options

A. Electric
B. Chemical
C. Air
D. Solar

Explanation

The correct answer to the question is "electrostatic."

Step-by-step solution:

1. **Understanding the Function**: The question describes a device that removes minute particles from smoke using electricity. This indicates that the device operates on principles of electrostatics.

2. **Identifying the Device**: The device in question is known as an "electrostatic precipitator." This device uses high voltage to create an electric field that charges the particles in the smoke.

3. **Mechanism of Action**: As smoke passes through the electrostatic precipitator, the charged particles are attracted to oppositely charged plates within the device. This process effectively captures the particles, leading to cleaner air.

4. **Application**: Electrostatic precipitators are commonly used in various applications, including industrial settings and in vehicles, to reduce air pollution by removing particulate matter from exhaust gases.

5. **Conclusion**: Therefore, the blank in the question can be filled with the word "electrostatic," making the complete statement: "The electrostatic precipitator is a device that removes minute particles present in smoke by applying electricity through it and attracting the particles towards itself."
