When ice is melting at 0°C, it undergoes an isothermal process maintaining a constant temperature. This is crucial for the phase change to occur smoothly.
During the process of melting ice, when a cube of ice is placed in a container at a temperature of 0°C, it undergoes a constant-temperature process known as isothermal process.
This is because while the ice is melting and transitioning into water, the temperature remains constant at 0°C before all the ice has melted.
This type of process is essential in maintaining thermal equilibrium until the entire phase change is complete.
