Assertion (A): The temperature of a metal wire rises when an electric current is passed through it.
- This statement is true. When an electric current passes through a metal wire, the electrical resistance of the wire causes some of the electrical energy to be converted into heat energy, leading to an increase in temperature.
Reason (R): Collision of metal atoms with each other releases heat energy.
- The collision of metal atoms with each other releases heat energy. This phenomenon is called the Joule effect or Joule heating. When an electric current passes through a metal wire, the free electrons in the wire collide with the metal atoms. This collision transfers kinetic energy to the metal atoms, which manifests as heat.
Therefore, the correct answer is: Both A and R are true, but R is not the correct explanation of A.

Consider the following statements and select the correct code.Assertio...
Assertion: The temperature of a metal wire rises when an electric current is passed through it.
Reason: Collision of metal atoms with each other releases heat energy.
The correct code for the given statements is option A, which states that both the assertion and reason are true and the reason is the correct explanation of the assertion.
Explanation:
When an electric current is passed through a metal wire, the temperature of the wire rises. This phenomenon is known as the Joule heating effect or resistive heating. It can be understood through the following explanation:
1. Joule Heating Effect:
When an electric current flows through a conductor, such as a metal wire, it encounters resistance. This resistance causes the collision of free electrons with metal atoms in the wire. The collision transfers energy to the metal atoms in the form of kinetic energy, which leads to an increase in their random motion. This increased random motion of metal atoms results in an increase in the temperature of the wire.
2. Collision of Metal Atoms:
The reason behind the rise in temperature during the flow of electric current is the collision of metal atoms with each other. These collisions release heat energy due to the conversion of electrical energy into thermal energy. The energy transferred during collisions is responsible for the rise in temperature of the metal wire.
3. Explanation of Assertion and Reason:
The assertion is true as the temperature of a metal wire does rise when an electric current is passed through it. This is a well-established phenomenon known as the Joule heating effect. The reason provided is also true as the collision of metal atoms with each other releases heat energy, which is responsible for the rise in temperature. Therefore, the reason is the correct explanation of the assertion.
Conclusion:
Based on the above explanation, it can be concluded that both the assertion and reason are true, and the reason is the correct explanation of the assertion. Hence, option A is the correct code for the given statements.
Reason: Collision of metal atoms with each other releases heat energy.
