Answer:
False
Explanation:
It is not true that this is an example of a chemical reaction. This is a typical example of physical reaction.
Most physical changes are often phase changes.
- A phase change is a change in the physical state of a body.
- In this change, it is from solid to liquid.
- Now new substances are formed.
- When substances are changed from one form to another, it is a physical change.
In a chemical change, a new substance is formed at the end of the process.

Answer:
ya thats right
Explanation:
here is one explanation i found on the web:
Answer: The true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
Explanation:
The electric force is due to the forces acting between the charges. The magnetic force is the force exerted between the magnets or moving charged particles.
The electromagnetic force is created by the magnetic field and the electric field.
The magnetic force is related to the electric force. These forces are different aspects of single electromagnetic force. The moving charge produce the magnetic force. The moving magnet produce the electric forces. The interplay of electric field and the magnetic force is the basis for motor.
Motor converts the electrical energy into mechanical energy. The operation of a motor depends on the relationship between electric and magnetic forces.
Therefore, the true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
