If the door of a refrigerator is kept open, then which of the following is true

Options

A. gets cooled
B. gets heated
C. neigther gets cooled nor gets heated
D. gets cooled or heated depending on the initial temperature of the room

Answer

To solve the question regarding the effects of keeping the door of a refrigerator open, we can break it down into several steps:

### Step-by-Step Solution:

1. **Understanding the Function of a Refrigerator**:
- A refrigerator works by removing heat from the inside and transferring it to the outside environment. It uses a working fluid (refrigerant) that absorbs heat from the interior and releases it outside.

2. **Effect of Keeping the Door Open**:
- When the door of the refrigerator is kept open, the refrigerator continues to function and tries to cool the air inside. However, since the door is open, the refrigerator is not just cooling the air inside but also absorbing heat from the surrounding room.

3. **Heat Absorption**:
- With the door open, the refrigerator absorbs more heat from the room than it can effectively remove. The working fluid inside the refrigerator will evaporate and absorb heat from the room air.

4. **Heat Rejection**:
- The absorbed heat is then rejected to the condenser outside the refrigerator. Since the refrigerator is continuously working to maintain a low temperature inside while the door is open, it will reject more heat into the room.

5. **Resulting Temperature Change**:
- As a consequence of the increased heat rejection from the refrigerator into the room, the overall temperature of the room will increase. This is because the refrigerator is expending energy to remove heat from the room while simultaneously releasing more heat back into it.

6. **Conclusion**:
- Therefore, if the door of a refrigerator is kept open, the room will get heated up due to the excess heat being rejected into the environment.

### Final Answer:
If the door of a refrigerator is kept open, the room will get heated.
