Question

The melting of ice is an example of a process that is: Select the correct answer below: always spontaneous always nonspontaneous spontaneous or nonspontaneous depending upon the temperature of the surroundings and pressure spontaneous or nonspontaneous depending upon the source of energy that is present

Answer 1

Option C, spontaneous or nonspontaneous depending upon the temperature of the surroundings and pressure

Step-by-step explanation:

AT room temperature, the temperature is favorable for ice to melt and hence melting of ice at room temperature is spontaneous but when the temperature is below the melting point and even then the ice melts then it is called non spontaneous. In this case, the enthalpy and entropy together create a positive change in the free energy for melting.

Hence, option C is correct
