Discuss the change in energy and arrangement of molecules on increasing temperature of ice from `-5^(@)`C to `10^(@)` C at 1 atm pressure.

Explanation

To discuss the change in energy and arrangement of molecules when the temperature of ice increases from -5°C to 10°C at 1 atm pressure, we can break it down into several steps:

### Step 1: Understanding the Starting Point
- **Initial State**: Ice at -5°C
- **Molecular Arrangement**: In this state, the water molecules are closely packed in a solid structure, forming a crystalline lattice. The kinetic energy of the molecules is low, and they vibrate in fixed positions.

### Step 2: Heating Ice from -5°C to 0°C
- **Temperature Change**: As we increase the temperature from -5°C to 0°C, the ice remains in the solid state.
