A glass full of hot milk is poured in the table. It begins to cool gradually.
Which of the following is incorrect?

Options

A. The rate of cooling is constant till milk attains the temperature of the surroundings
B. The temperature of milk falls off exponentially will time.
C. While cooling, there is a flow of heat from milk to the sourroundings as well as from surroundings to the milk but the net flow of heat is from milk to the surroundings and that is why it cools.
D. All three phenomenon, conduction, convection and radiation are responsible for the loss of heat from milk to the surroundings.

Explanation

To solve the question regarding the cooling of hot milk poured on a table, we need to analyze the statements provided and determine which one is incorrect.

### Step-by-step Solution:

1. **Understanding the Cooling Process**:
- When hot milk is poured onto a table, it begins to cool down due to heat transfer to the surrounding environment. This cooling occurs through three primary mechanisms: conduction, convection, and radiation.

2. **Analyzing the Statements**:
- We have four statements to evaluate:
- **Statement A**: The rate of cooling is constant till milk attains a temperature of the surrounding.
- **Statement B**: The temperature of the milk falls off exponentially with time.
- **Statement C**: While cooling, there is a flow of heat from milk to the surrounding as well as from surrounding to the milk, but the net flow of heat is from the milk to the surrounding.
- **Statement D**: All the phenomena (conduction, convection, and radiation) are responsible for the loss of heat from milk to the surrounding.

3. **Evaluating Each Statement**:
- **Statement A**: This is incorrect. According to Newton's Law of Cooling, the rate of cooling is not constant; it decreases as the temperature difference between the milk and the surroundings decreases.
- **Statement B**: This is correct. The temperature of the milk does fall off exponentially with time as it cools.
- **Statement C**: This is correct. Heat flows from the milk to the surroundings, but there is also some heat transfer from the surroundings to the milk, although it is less than the heat lost by the milk.
- **Statement D**: This is correct. Conduction, convection, and radiation all contribute to the cooling process.

4. **Conclusion**:
- The incorrect statement is **Statement A**. The rate of cooling is not constant and decreases over time as the temperature difference reduces.

### Final Answer:
The incorrect statement is **A**: The rate of cooling is constant till milk attains a temperature of the surrounding.
