During summers in india, one of the common practice to keep cool is to make ice balls of crushed ice, dip it in flavored sugar syrup and sip it. For this a stick is inserted into crushed ice and is squeezed in the palm to make it into the ball. Equivalently in winter in those areas where it snows, people make snow balls and throw around. Explain the formation of ball out of crushed ice or snow in the light of P - T diagram of water.

Explanation

To explain the formation of a ball out of crushed ice or snow using the P-T (Pressure-Temperature) diagram of water, we can break down the process into several steps:

### Step-by-Step Solution:

1. **Understanding the P-T Diagram**:
- The P-T diagram for water shows the relationship between pressure (P) and temperature (T). The phase changes of water (solid, liquid, and gas) are represented in this diagram.
- At standard atmospheric pressure (1 atm), ice melts at 0°C (273 K) and water freezes at the same temperature.
