Statement-1: Work and Heat are two equivalent form of energy.
Statement-2: Work is transfer of mechanical energy irrespective of temperature-differene whereas heat is transfer of thermal energy because of temperature difference only.

Options

A. Statement-1 is true, statement-2 is true, statement-2 is a correct explanation for statement-1
B. Statement-1 is true, statement-2 is true, statement-2 is NOT a correct explanation for statement-1
C. Statement-1 is true, statement-2 is false
D. Statement-1 is false, statement-2 is true

Answer

To analyze the statements provided in the question, we can break down the concepts of work and heat in thermodynamics.

### Step-by-Step Solution:

**Step 1: Understanding Statement 1**
- Statement 1 claims that work and heat are two equivalent forms of energy.
- This is a fundamental concept in thermodynamics. Both work and heat can be converted into each other and are forms of energy transfer.

**Step 2: Understanding Statement 2**
- Statement 2 explains the nature of work and heat. It states that work is the transfer of mechanical energy irrespective of temperature difference, while heat is the transfer of thermal energy due to a temperature difference.
- Work is done when a force is applied over a distance, and it does not depend on temperature. For example, pushing an object involves work done, regardless of the object's temperature.
- Heat, on the other hand, is energy transferred between systems or objects due to a temperature difference. For instance, when you place a hot object next to a cold one, heat flows from the hot object to the cold one.

**Step 3: Evaluating the Statements**
- Both statements are correct. Statement 1 accurately describes the relationship between work and heat as forms of energy. Statement 2 correctly explains the conditions under which work and heat are transferred.
- Since Statement 2 provides a valid explanation for Statement 1, we conclude that Statement 2 is indeed a correct explanation of Statement 1.

**Step 4: Conclusion**
- Therefore, both statements are true, and Statement 2 is a correct explanation for Statement 1.

### Final Answer:
Both Statement 1 and Statement 2 are correct, with Statement 2 providing a correct explanation for Statement 1.
