The amount of heat given to a system in a cyclic thermodynamical process-

Options

A. is completely changed with work
B. is completely changed into internal energy
C. Brings about reduction in temperature
D. Brings about increases in temperature

Explanation

To solve the question regarding the amount of heat given to a system in a cyclic thermodynamical process, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Cyclic Process**:
- In a cyclic thermodynamic process, the system returns to its initial state after completing the cycle. This means that all thermodynamic properties such as pressure, volume, and temperature are the same at the beginning and the end of the process.

2. **Applying the First Law of Thermodynamics**:
- The first law of thermodynamics states that the change in internal energy (ΔU) of a system is equal to the heat added to the system (Q) minus the work done by the system (W):
\[ \Delta U = Q - W \]

3. **Internal Energy in a Cyclic Process**:
- Since the initial and final states are the same in a cyclic process, the change in internal energy (ΔU) is zero:
\[ \Delta U = 0 \]

4. **Relating Heat and Work**:
- Substituting ΔU = 0 into the first law equation gives:
\[ 0 = Q - W \implies Q = W \]
- This means that the total amount of heat given to the system is completely converted into work done by the system.

5. **Conclusion**:
- Therefore, in a cyclic process, the amount of heat given to the system is equal to the work done by the system, and there is no change in internal energy.

### Final Answer:
- The correct statement is that the amount of heat given to the system is completely converted into work done by the system.
